Ludomusicians, rejoice! The Xbox 360 version of Rock Band 2 received a massive title update earlier today, adding a whole slew of oft-requested features to Harmonix's beefy music platform. The most notable of these additions is that the game now supports wireless microphones, such as those used with Lips. Other changes include improved hammer-ons and pull-offs, background downloading for music store purchases and the "Audition Mode," which allows Rock Band Network users to test out their homebrewed Rock Band tracks.
