Fixing logic issue with next/prev btns
Changed two line instance to one
Updated name of function to better describe functionality
Now Supporting switched power

Added code tons support the app when using switched power instead of
constant charging. Unfortunately I killed my battery too many times
leaving the screen on and having the tablet constantly charging. This
will fix that.
I also no longer hold a constant CPU wake lock. Doesn’t seem to have
broken anything but it should be noted.
Debugging for issue with the music player

Music player doesn’t work til you try to hit play twice when the app
has just booted. This is retarded.
