I've thought about that, but, it's just not the same. After all, you'll eventually run out of unplayed songs to swap it with (especialy in small playlists). And I admit, if this is a problem frequently, then the song or songs shouldn't be in the playlist to begin with.

My main thought is that it could be quicker to append a playlist and remove one or more tracks or groups of tracks, rather than 'append track', 'append track', 'append track', ad nauseum, to get to the selection of music that you want.
