Unsupported Players

[GoneMAD]

As of right now, these players do not broadcast their playing information so there is no way to support them. Broadcasting out intents for playing songs is about an hours worth of development (it is very easy) so I would recommend putting in requests to the developers of these players asking to add support.

Pandora
MOG
Jet Audio (scrobbling feature is broken in the app so support is not possible)

Those with android 4.4 will now be able to use the notification listener to support pretty much every player. Enable it in the settings.
