let's replace allmusic.
allmusic: Great resource. Crappy interface before their redesign (thanks for the javascript-based links!), unusable piece of shit now. These guys are supposedly a small company with good intentions but either they're stupid, or they're crippled by having to make money with the site. Also, the web needs open APIs to a database like this, but instead allmusic is locking away more of their content behind registrations and tabbed interfaces.
wikipedia: Awesome and getting better. If a definition is wrong, you change it -- no emailing support and never getting a reponse. There's no wikipedia API yet that I know of, but it's a matter of time.
So come on people. Let's do the wikmusica! Let's burn down Allmusic! The music database to end all music databases! Open standards! Community for community!
er, actually I don't have time. Somebody please get cracking.
