Media down loader

Im looking for a good media downloader(mp3,mpeg,avi) for linux. I would really like a clone of WinMX. Right now im using gtk-gnutella 0.9. But it dosnt do multi user download, and I cannt search for an artist/band and the song name. I REALLY want that. It would also be great if it had something so I could select the media type (mp3, mpeg, avi, ect)

While im on the subject of media...

I have a Turtle Beach Santa Cruz sound card. I have sound but its not for my sound card. So surround sound dosnt work. I would really like it to. There page dosnt have the drivers for linux or the source. So if anyone knows were I can get the drivers Id be very great full.

Ill keep looking for both and post if I find anything.

Thanks
Nuke
