Found what looks to be an excellent "open-source" online music information resource called MusicMoz:

About MusicMoz - The Open Music Project

Music information is one of the most searched topics online and a very important application of the internet. Commercial and fan websites offer an abundance of information on thousands of bands, artists, orchestras, composers and just about every other aspect of music. One of the biggest drawbacks to this wealth of information is that it can be very disorganized and can often disappear as websites continually shut their doors.

Based around the Open Directory editing model, MusicMoz aims to be a comprehensive directory of music, built by volunteers around the world, with contributions from the web public.

The site also appears to be blessedly free of popups, lurking spyware, and the like -- which by itself makes it an improvement over most "music" sites.
