Unfortunately it is US only, so it fails to be a game changer, but I guess congratulations are in order.
Worse, usually once this kind of companies get deals with record companies, they close their sites to non-US users. It's what happened with Pandora and Last.fm, also Hulu on the video scene.
Perhaps Chris (physcab) can clear up some of these issues for us?
While I can't talk specifically about the deal terms, I can say that we are very pleased with the agreement and think it represents forward progress for the industry.
If any of you guys have further questions, I would encourage you to contact our PR guy who is normally very responsive.
