Does anyone here use Discogs? User-contributed discographies, some supplemental artist data (sometimes a lot), and not limited to commercially released CD's, includes lots of vinyl-only releases, cassette tape, etc.

Some of the Amazon CD data can be downloaded, not sure of the licensing arrangements. Discogs data can be downloaded. I'm using a local cataloging database application, CATraxx, which is able to query both databases with ease.
