Be nice to have a lyrics scroller, if it can be implemented.

But, another idea hit me on the head the other day.
With standard CD players it's possible to play a selection of tracks without creating playlists. ie Press the "Program" button -> select a number of tracks -> hit play. As the tracks are played they are dropped from the list (unless you select replay for any particular track).

Playlists are OK, but they're permanent until you spend time editing, adding and removing tracks, which is a bit time consuming in most cases.

Just a thought..... only a thought.
