The quick answer is you can't, really. The longer answer is this: There are some mp3 players (i.e. Soritong) that allow you to play the mp3s in "Karaoke" mode. All it really does is mute the "middle channel"-- the parts of the band that sound like they're coming from in between the two speakers. Normally, the vocals reside there, and as a result you have a fairly decent "non-vocal" effect. This works for some songs better than others, though. Justin Miller Geneva College
