The Wall Street Journal mentioned MusicBrainz in an article on music metadata today. While talking about using acoustic fingerprints to identify music they write:
MusicBrainz offers a program called MusicBrainz Tagger that uses this method, and Gracenote expects its software partners to broadly roll out a similar Gracenote technology this year. You have to download special software for this system to work on your PC.

I’m glad to see that Gracenote is still playing catch-up with MusicBrainz. Somewhat ironic, isn’t it?
