Using Songkick.com, you can actually pull in the artists of other users and load them into your account. (From Pandora and Last.fm). So guess what? Mistype your own account name or pick one at random? You get all 347 of their favorite artists in your account. No worries, their UI allows you to delete them “one at a time”.
Don’t you just love UI design “break” throughs? Yes, pun intended.
