Do you mean the difference between Pause and Stop? If so:
Pause - music controls appear in top bar when you adjust volume using volume rocker. In other words, to resume playback of the song, all you have to do is press ">" (play). Also, these same controls appear at the top of the lock screen, meaning even if your phone is otherwise locked, you can still resume playback of the song.
Stop - Song is stopped and unable to be resumed, unless you go back into the Zune application and press play.
Naturally, I'd like to be able to STOP a song so I don't accidentally resume playback of a song while in a meeting or class or a socially inappropriate situation.
