I've always wanted to be able to leave Audiosurf running at parties on casual mode, so you either have an awesome visualizer or people can jump on and off the game as they like, all without the music ever stopping.

Is there a mod where you can que up songs to play automatically one after the other, without having to go and select a new song at the end of every last song?

I would just edit all the songs together but the different tempos would make for some incredibly boring sections of track.
