Microsoft announced at their E3 keynote last month that Last.fm would be coming to Xbox Live. Joystiq is working on an interview with key players at both Last.fm and Microsoft to bring you more details about the collaboration soon. However, they can share one tidbit: today Joystiq spoke with Christina DeRosa, a general manager for XBL, and she let them know who the service will be available to.
"Silver users will be able access what we're considering a trial period of three hours a month, which comes with video advertising. Gold users will have unlimited ad-supported access, so they can use it 24 hours a day. There will also be a premium offering on a subscription basis from Last.fm, that will be commercial free and will also have more sophisticated personalization features, like Loved Tracks."
