What’s the history here? I know Amazon initially bought MusicBrainz database when Amazon created Soundunwound.com, which was Amazon’s own music wiki, which also was used by Amazon as a source for artist info on Amazon.com itself. Amazon users then expanded the Soundunwound.com database (adding artist bios, publicity photos, album covers - all the important visuals that wikipedia is too scared to use) so it was better than MusicBrainz. And then… Amazon shuttered Soundunwound.com (though most of the content still exists inside Amazon.com).
