YouTube Music wants to make it easier for you to check out music recommendations on Android 12. It will automatically display recent albums and playlists when connecting an audio device like headphones or Bluetooth speakers. It'll also show up in your Quick Settings. There's the app icon and app name in the top-left corner. When you open Quick Settings, six albums are on display, while the lockscreen can show you three.
If you tap on any of the albums, it'll immediately start playback and switch you to the Now Playing controls. 9to5Google reports seeing the recommendations consistently when connecting headphones on Android 12.
