ArtistData

Interesting site passed my way. ArtistData is a new service that updates your twitter, facebook, myspace feeds all at once, and claims "Artists should only enter data once."

"ArtistData tirelessly works to give musicians more time to be creative. We're building solutions to automate the monotonous updating of artist websites, social network profiles, concert databases, Twitter, official news feeds, iCal, local press, fan newsletters, and even tour books. When an artist updates our site, we update all their sites. Our current users save hundreds of hours, giving them more time to do what they love: create music."
