FN Music Extension

Shows the currently playing track and artist in Floatifications (Floating Notifications) along with buttons to control your music (play/pause/next/previous).
Tapping on the next in the notification will launch the player of your choice (you must select the player to launch in the preferences).
Pro features:
-Show album art instead of default icon
-Automatic downloading of album art
-Customize what info is displayed and how it is formatted
The album art feature works with many players but some players that use their own database might not work, so be sure to use the album art test before purchasing.

Works with most music players.
If your player does not work, try the suggestions below.
If it still doesnt work then your player is not compatible because it does not broadcast out what its playing.
Android 4.4 : Enable the Notification Listener setting to support any player that also supports the android lockscreen music controls.
Android 4.3 and earlier: If your player has last.fm scrobbling support, enable that.
If not, look for a setting to broadcast metadata and enable that.
