While it will most definitely end up being a huge week for announcements, there has only been one rhythm game, so far, with a substantial list of songs confirmed that was added to the Rhythm Game Track Finder. Earlier today, “Rock Band 2” confirmed their full track listing, and all 83 songs that will be appearing on the disc have made their way into the Track Finder. Artists like AC/DC, and Bob Dylan will be making their console rhythm game debut, alongside a premiere track off of the long awaited “Chinese Democracy” from Guns ‘N Roses.

“Rock Band 2″ may be the only game that was added to the Track Finder, but there was other rhythm game news that was drummed up earlier today at the Microsoft press conference. Red Octane announced that “Guitar Hero World Tour” will see a partnership the ultimate rockers, Metallica, for content exclusive to their game. Also, Microsoft officially announced “Lips” for the Xbox 360, an innovative new karaoke game from iNiS that will allow you to import your own songs and sing along with them. There’s no doubt that the Track Finder will see updates for both these titles in the coming weeks, so check back often.

In keeping with tradition, today’s update is below:
