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.
(reprinted without permission and in fear of the WSJ striking me down)
I’m glad to see that Gracenote is still playing catch-up with MusicBrainz. Somewhat ironic, isn’t it?
