MTV/Viacom announced today that The Beatles have agreed to let their music be used for the video game Rock Band. This is great news as up until now they have signed NO digital music deals. No iTunes, no Rhapsody, no Napster, no nothing. You can hear The Beatles in radio formats (including on the Rhapsody Channels), but not purchase or streaming. Hopefully this is the beginning of an experiment that will let the music of The Beattles be available everywhere.
