For anybody in the UK who is missing Pandora since it was blocked (and indeed anybody in the US who wants to have a look), check out Grooveshark, I think it's amazing. Like spotify, but in a browser, no (audio) adverts, and free.
Would the work being carried out for the Pandora Player be transferable to other internet radios, such as Grooveshark?
Cheers,
Matt.
