Could you implement cover preview in the minimized player, similar to how spotify has it.
This would make it even easier recognizing which track you are playing, besides reading the track title.
It also looks visually appealing and professional.
At the same time you could implement the ability to switch titles by swiping left/right gesture within the minimized player: Open Imgur
This way the "play next track" button could be removed from Deezers minimized player, leaving only the play button at the right end, with the heart button to it's left, as you can see in Spotify's example. And the left end of the minimized player would be reserved for the cover picture.
I think these two ideas would greatly improve the minimized player, and therefore also the UX.
