Okay, I know the site isn’t really dead but it’s dead to me…! *cries* And only because I live in the UK. Pandora got threatened asked nicely to stop people from outside the US using their service a while ago. Quite a long while ago actually so this is news to no one but…
I found a replacement.. kind of. It’s not the same but MeeMix.com does the same kind of thing as Pandora used to. Sure, you could get on a proxy server based in the US to circumvent Pandora’s IP filtering but I’ve found that to be extremely unreliable and slow.
Guess how I found Meemix though? Via a Facebook advert. I don’t know if that’s a good thing or a bad thing! The interface is kind of clunky and overly flash-based. They’re trying to make it more of a social network type site which is horrible so steer clear of that bit of it. I don’t know if it works using just user responses to decide what song to play next or some elaborate algorithms but hey, it works in the UK so whatever.
Actually, MeeMix has some pretty neat stuff which Pandora didn’t have.. The “mood control” bit allows you to fiddle with two settings which change the selection of tracks. “Surprise Me” and “Pulse”. The higher you set the “Surprise Me” slider, the more likely songs selected are going to Surprise you. *BOO* <- Not like that. The higher “Pulse” is the more the selections go “party time” and the lower it’s set, the more relaxing. Also, MeeMix has integrated YouTube videos of the current song a click away and believe-it-or-not a bunch of links to share the content on your favourite social network.
It’s okay, but it’ll never fill the void Pandora has left behind… 
i have friends in canada that get around pandora blocking by just using tor, apparently the music streams arn’t blocked just the website, so you tor to the website and normal connect to everything else.
