Can you hear MP3's? I have prepared a medley of different styles of things I've created using the PSR-500. The only "automation" I used was creating my own drum rhythm. I did sometimes keep the onbard fill-ins but reprogram the main beat. Evrything else was played live in the onboard sequencer. Then the vocals were mixed in using a multi-track tape recorder (and later Cool Edit Pro for reamstering). So I guess you're right, anything better will be a breath of fresh air.

I won't leave it on my server for too long. You can download it at this address:
