To get started with Uber Music, you'll need to connect your Spotify Premium account to your Uber account on the Uber Profile screen.
When you open the app, just tap the Profile icon in the top left corner, then head to your account page. You will see the option to connect to your Spotify account.
Once you've entered your Spotify account information, you'll be good to go! You can request an Uber ride using any vehicle type (uberX, UberBLACK, etc.) as usual.
If you are connected with a vehicle that is music-enabled, you'll see a music bar appear at the bottom of the Uber app. Tap that bar, and select a song from one of your Spotify playlists. As soon as your driver begins the trip, your music will start playing! From there, you can wirelessly control your music through the Uber app or your Spotify app for the duration of your trip.
If you're on an Android device, tapping the music bar will redirect you to your Spotify app, and you can play your music from there. We are working on in-app integration for Android - stay tuned.
Enjoy your ride!
