There's no better way to end the week than with a hefty helping of confirmed Rock Band downloadable content for next week. It's one of those small things that makes life all the more enjoyable and brighter. Anyway, let's get to it. Next Tuesday, May 13th Harmonix will be adding "Hanging on the Telephone" by Blondie, "Train in Vain" by The Clash and "Kool Thing" by Sonic Youth to the Rock Band DLC library. Each track will be 160 Microsoft points and only available individually, which means no money saving three pack for you. So ... yippy for Blondie?
