 Roadmap of major planned features in rough order that I plan to work on them in (little features get sprinkled in wherever):
 
-Gapless Playback (may not be possible to get perfect)
-	-Media Player chaining (in progress)
-	-4.1+: setNextMediaPlayer?
 HLS Video
 	-Display video where album art is currently (double tap to fullscreen)
 	-Videos can play inline with songs
