YEAH! <agrees with Guu>
MP3's are pretty bad, expecially at low bitrates. WMA 9 audio and OGG Vorbis are actually much better audio formats than MP3 at equivalet bitrates.

But anyway, to keep this on topic...

Kinji, another thing to try: You should check your volume settings as well. Sometimes, if you have a microphone on your computer and it is enabled and turned up, it can feedback thru your speakers. Also, some soundcards have a weird "3d sound" option that can mess up the playback through the speakers. If you see anything weird in the volume control, try muting it and see if that helps.
