Adjustments to user handling of Stereo

Per VC discussion:
- Pressing STOP does not NULL your selected song
    - ...unless you press it a second time while already stopped
- Pressing PLAY should de-activate pause if active, not restart the track
- Pressing PAUSE while paused should not de-activate pause
- Removed the Extra functionality from TRACK.
