They also say that he sucks the moisture out of ducks.
But for the topic. First of all I don't see a reason why you would want to listen music while playing LFS. But if you really want to there's no reason why you should play them with LFS as ogg. You can use ie. JetAudio or Winamp, make a good playlist and add some hotkeys so you can use them to change song / volume / rewind etc.
If you have to listen to music while you race, wouldn't it just be simpler to have Windows Media Player or iTunes or RealPlayer or WinAmp on in the background, instead of going to the trouble of converting everything into .ogg?
