I think it would be good to have the option in Emplode or JEmplode to "Replace" a current track.

Recently I've been re-ripping a bunch of stuff and when I put it back on the player I find I need to be really carefull to check each track to see if it has refs to other playlists (and many of them do). Sometimes with popular tracks, I have to look through a dozen playlists so that I can make everything as it was.

Having a Replace feature would let you drag a new mp3 track onto the player directly over an existing track, deleteing the existing track and replacing it with the new one in any playlist it was associated with.
