I would like to change the behavior of shuffle from a global behavior switch to a context specific action.  Currently, when you press the shuffle button, the player goes into shuffle mode, and all subsequent playlists, albums, etc. are shuffled.  I want the button to work like the play button, but to play the current playlist in random order.

I generally want to listen to the tracks of an album in order, but occasionally I want to change the order of one album, for one play.  With the current shuffle behavior, I have to remember to turn off shuffle afterwards, which I often forget to do.
