Google does something nice ...
Over at the MusicBrainz blog, Mayhem indicates that Google has pledged $15,000 to support the MetaBrainz foundation. MetaBrainz is the non-profit organization behind MusicBrainz, the community music 'metadatabase'.
MusicBrainz provides all sorts of interesting data about artists, albums and tracks and provides web services APIs to access the data (or you can just download the data and create your own postgresql database).
Good for Google!
