Is the "Media-style notification" broken for anyone else? Since about a week ago I now

• no longer see the large album art in the notification, and
• no longer see the album art on my lock screen.

I believe it's because they changed the number of action items in the notification bar. Android Media-style (in the support library) allows you to put up to 3 action items on the notification. If you put more than 3, Media-style fails and it reverts to ordinary notifications. Spotify recently switched from 3 action items (rewind, play/pause, fast-forward) to 4 action items (add to My Music, rewind, play/pause, fast-forward), so I think this is what caused the problem.

I'm on Android version 6.5.0.1816, Android v6.0.1
