Pandora internet radio service

Pandora is on my experience the best radio service on the web. Actually it is more than a radio because is the user who decides which kind of music to play. The users can build radio stations and the streaming quality is great.
But as I write I can't use Pandora anymore because of some law restrictions limited Pandora to offer their service outside of US! veeery bad.
