The music on this site is encoded in ogg vorbis; an explanation for why I use ogg is given here. These ogg files are of very high quality, and worth the time it takes to download them. For playing Ogg vorbis files on a Windows install I recommend WinAmp (a more recent version if you have an old install.) Ogg vorbis freeware for your choice of platform can be found here and here.
