The most complete site and my favorite is:
Mysterious Way's Music
It is so thorough and includes links to lyrics and downloads.
Another very reliable source is:
Mysterious Ways - Official Lion's Gate Site
The episode guide has detailed music info under each show listing.
And there are many out there who would like to download some of the music. My favorite site since the downfall days of Napster is:
Not only can you download music but can find audio and video files as well as video games. It is worth downloading the program.
