Android Auto Default Music Player: How to Set, Change, and Control It

You connect your phone to the car, and Spotify starts blasting. Again. You never asked for it. You just want YouTube Music to play, or maybe nothing at all until you're ready. Sound familiar?

You're not alone. We hear this constantly from customers at Car Tech Studio.

The Android Auto default music player is one of the most frustrating things for drivers to figure out. And the reason it's frustrating is simple: there isn't one single setting that controls it. It's spread across multiple apps and menus.

In this post, I'll break down exactly how it all works and show you how to fix it.

Key Takeaways

• The Android Auto default music player is controlled mostly by Google Assistant's Music settings, not by Android Auto itself
• To change which app plays when you say "Hey Google, play music," you need to update the setting inside the Google app on your phone
• Android Auto also has a "Start music automatically" toggle that controls whether music starts when you connect your phone
• Apps like Spotify can auto-play due to Bluetooth behavior from your car itself, not just Android Auto
• Local players like Poweramp cannot be set as Assistant default providers
• Services like Tidal are also not available in the default provider list
• You can use "No default provider" as a workaround, but it has a known bug where it may reset to YouTube Music after roughly 24 hours

Why Android Auto Doesn't Have a Simple "Default Music Player" Setting

I know. You'd expect to find something like "Choose default music app" inside Android Auto settings. Tap it, pick Spotify or YouTube Music, done.

But that's not how it works.

Android Auto is really just a projection layer. It puts your phone's apps onto your car screen in a driving-friendly format. The actual decision of which music app to use when you issue a voice command is made by Google Assistant, not Android Auto.

So when you say "Hey Google, play music," it's Assistant that decides which app to open. And that setting lives in a completely different place.

This is why so many people change things in Android Auto and still see the same app launch. They're changing the wrong setting.

The Three Layers That Control Your Default Music Player

Before diving into the fix, it helps to understand what's actually going on. There are three main layers at play here.

Layer 1: Google Assistant's Default Music Provider

This is the most important one. Whatever service you've selected in Google Assistant settings is what plays when you give a generic voice command like "play music" or "play some jazz."

Supported services include YouTube Music, Spotify, Apple Music (in some regions), Deezer, and Pandora. That's a short list, and we'll talk more about what happens if your app isn't on it.

Layer 2: Android Auto's Auto-Play Settings

Android Auto has its own settings for what happens when you plug in or connect wirelessly. The main one is called "Start music automatically." When it's on, Android Auto will start playing media as soon as you connect — usually picking up where you left off with whatever app you last used.

This is separate from Assistant's default. You can have Spotify set as your Assistant default but still have YouTube Music auto-resume if that was the last thing you used.

Layer 3: Your Car's Bluetooth Behavior

This one surprises a lot of people. Your car's head unit can also trigger music playback. Some vehicles send an automatic "play" command when your phone connects via Bluetooth, which can start an app even if you've turned off Android Auto's "Start music automatically" toggle.

If you've already changed your settings but music keeps starting, your car might be the one causing it.

How to Change the Default Music Player in Android Auto

Here's how to actually fix this, step by step.

Step 1: Change the Default in Google Assistant

This is where most people need to start.

On your phone:

• Open the Google app
• Tap your profile picture in the top right
• Go to Settings
• Tap Google Assistant
• Scroll down to find Music under the Services section
• Select the music service you want as your default

Once you save this, any generic "play music" command in Android Auto will open that app.

If you use the Google Home app instead, you can also get there by opening Home, tapping your profile picture, going to Home settings, and selecting Music.

Step 2: Adjust Android Auto's Launcher

Open the Android Auto app on your phone and go to Settings, then Customize launcher. This lets you choose which apps appear on your car's screen.

You can uncheck apps you don't want to see or use. This doesn't change your Assistant default, but it does reduce the chance of accidentally launching the wrong app and having it remembered as the "last used" app.

Step 3: Turn Off "Start Music Automatically"

If you don't want music to start the moment you connect your phone, here's how to turn that off:

• Go to Settings on your phone
• Search for Android Auto and open it
• Find the Start-up section
• Toggle off "Start music automatically"

On some devices running Android 11 or later, you'll find this under Settings > Connected devices > Connection preferences > Android Auto.

Once this is off, your car will connect without any music playing until you decide to start it.

How to Stop Spotify from Auto-Playing on Android Auto

Spotify gets more complaints about this than any other app. Multiple support threads describe it as aggressively taking over the head unit whenever you start the car. Here's how to stop it.

First, Turn Off "Start Music Automatically"

I already covered this above, but if you haven't done it yet, start here. It's the most direct fix.

Change or Remove Spotify as Your Assistant Default

Go into Google Assistant's Music settings (as described above) and either switch the default to a different app or select "No default provider."

With no default set, Assistant will use whatever music app you invoked most recently instead of always defaulting to Spotify.

Restrict Spotify's Background Activity

Spotify can start in the background when your phone detects the car. To stop this:

• Go to Settings > Apps > Spotify > Battery
• Switch the setting to Restricted or Optimized

This limits Spotify's ability to launch on its own when Bluetooth connects.

Turn Off Spotify's Auto-Launch Permissions

On some phones, you can also:

• Go to Settings > Apps > Spotify > Special app access
• Turn off any auto-launch or background launch permissions

Check Your Car's Bluetooth Settings

If music is still starting after all of the above, your car is likely the one sending the play command. In your car's infotainment settings, look for options related to automatic media playback or Bluetooth auto-connect and disable them.

Alternatively, on your phone, go to your Bluetooth settings, tap the car's device name, and turn off Media audio. This stops the car from triggering media at all over Bluetooth — though it also means you'll need to use Android Auto for audio instead of standard Bluetooth.

What If Your Preferred App Isn't Available as a Default?

This is a real pain point for a lot of users. Here's the straight answer on the two most common cases.

Tidal

Tidal is not available as a default provider in Google Assistant settings. It simply doesn't show up in the list. This isn't a bug you can fix — it's a limitation of which services Google has chosen to integrate.

The workaround that works for some people is to select "No default provider" in Assistant settings, then explicitly say "play [artist] on Tidal" once. Android Auto tends to remember the last app you used, so it may continue using Tidal for future commands as long as no other app takes over.

Local Players Like Poweramp or Musicolet

Apps like Poweramp that play music stored on your device cannot be set as default providers in Google Assistant. They just aren't supported that way.

You can still use them. They'll show up in the Android Auto launcher if they support the Android Auto API. But Assistant won't route generic voice commands like "play music" to them. You'd need to say something like "play [song name] on Poweramp" or just open the app manually on the car screen.

The "No Default Provider" Option: Useful But Buggy

Setting "No default provider" in Google Assistant's Music settings is a useful middle ground. Instead of locking into one app, it uses the last service you explicitly invoked.

However, there's a known issue worth mentioning. Multiple users in Google Assistant support forums have reported that the "No default provider" setting resets itself to YouTube Music after roughly 23 hours, even without any user input. It seems to be a bug — or possibly intentional behavior — in how Assistant handles this state.

If you use this approach, you may need to check and re-set it periodically. Not the most stable solution, but it's the best workaround for people who want to use apps that aren't in the official default list.

Advanced Options for Power Users

If standard settings aren't giving you enough control, here are a few more things to try.

Developer Options

• Go to Settings > About phone
• Tap Build number seven times to unlock developer options
• Go back to Settings > Developer options
• Look for a Default apps section — some devices show a "Music player" field there

This varies by phone and Android version, so it won't work for everyone.

Automation Apps Like Tasker

Tasker and similar automation tools let you create rules like "if Android Auto is active, close Spotify." Some users have set up routines that detect when Android Auto turns on and immediately stop any music app from playing — so nothing starts until they manually choose something.

It's a more technical approach, but it gives you control that no official setting provides.

Samsung Modes and Routines

If you have a Samsung phone, check your Modes and Routines settings. A routine might be set to launch Spotify or another app when your car's Bluetooth is detected. Some users have found that the culprit wasn't Android Auto at all — it was a Samsung routine they'd set up and forgotten about.

A Note on Your Car's Head Unit

No matter how many phone settings you change, if your car is sending a play command over Bluetooth, something will start playing. This is especially common in older vehicles where the infotainment system tries to resume the last media source every time you turn on the ignition.

If you've tried everything on the phone side and music still starts on its own, go into your car's settings. Look for anything related to auto-start media, Bluetooth media, or audio resumption, and turn it off.

Your phone and your car are both part of this puzzle. Both need to be configured.

Upgrading Your Head Unit for Full Control

At Car Tech Studio, we work with a lot of customers dealing with older factory head units. And some of those units just aren't built for the way Android Auto works today. They have their own Bluetooth behaviors that no phone setting can override.

If that sounds like your situation, it might be worth considering a full upgrade.

A modern aftermarket head unit with built-in wireless Android Auto gives you full control over the media experience, with no weird Bluetooth auto-play triggers from old factory systems. We carry Android Auto head units and wireless CarPlay and Android Auto modules for a wide range of vehicles, from Toyota to BMW to Jeep. These units are designed to work cleanly with your phone and give you a modern in-car experience without the quirks of aging factory hardware.

Frequently Asked Questions

How do I change the default music player in Android Auto?

You change it through Google Assistant, not Android Auto itself. Open the Google app, tap your profile picture, go to Settings, then Google Assistant, then Music, and choose your preferred service. This controls which app plays when you say "Hey Google, play music" in the car.

Why does Spotify keep playing automatically when I start my car?

It could be caused by Android Auto's "Start music automatically" toggle, Android's media resumption feature, Spotify's background activity, or your car's Bluetooth sending an auto-play command. Start by turning off "Start music automatically" in Android Auto settings, then restrict Spotify's background activity under its battery settings.

Can I set Tidal or Poweramp as my default music app in Android Auto?

No, not as a formal Google Assistant default. Only a limited set of streaming services like Spotify, YouTube Music, and Apple Music appear in the Assistant's Music settings. Tidal and local players like Poweramp can still be used in Android Auto, but you'll need to open them manually or name them in your voice command.

What does "No default provider" do in Google Assistant?

It tells Assistant to use whatever music service you last used instead of defaulting to one specific app. It's useful if your preferred app isn't in the default list. However, there is a known bug where this setting sometimes resets back to YouTube Music after roughly 24 hours, so it may need to be re-applied occasionally.

Why does my music start even when "Start music automatically" is turned off?

Your car is likely sending a play command via Bluetooth when it detects your phone. This behavior comes from the car's infotainment system, not Android Auto. Check your car's settings for any Bluetooth or media auto-play options and disable them. You can also turn off "Media audio" in your phone's Bluetooth settings for the car as a workaround.

Does hiding an app in Android Auto's launcher stop it from being used as default?

No. Hiding an app in the Customize launcher section removes it from the car's visible interface, but it doesn't change your Google Assistant default. If Spotify is still set as your default provider in Assistant settings, voice commands will still open it even if it's hidden from the launcher.

Can automation apps help stop unwanted music playback in Android Auto?

Yes. Apps like Tasker let you build rules that detect when Android Auto is active and automatically close any music app, preventing auto-play entirely. Samsung users should also check Modes and Routines, which may have a routine set to launch Spotify or another app when the car's Bluetooth is detected.

Will upgrading my head unit fix Android Auto music default issues?

A modern aftermarket head unit with native Android Auto support tends to behave more predictably and gives you better overall control. Older factory head units sometimes have their own Bluetooth auto-play behaviors that interfere with your phone settings. Replacing the head unit removes that layer of complexity entirely.
