I have a lot of Rock Band DLC. Like, A LOT. This might be bad for my ability to get anything done.Harmonix's upcoming non-instrument controller using Rock Band game, Rock Band Blitz, finally has a release date and price. According to this official announcement, the game will officially arrive on PlayStation Network August 28, and Xbox Live August 29. It will retail for $14.99 and 1200 MSP respectively.Harmonix also announced four new songs for the 20-plus song soundtrack. Here's the whole soundtrack thus far, with the new songs in bold.All-American Rejects - "Kids In the Street"Avenged Sevenfold - "So Far Away"Barenaked Ladies - "One Week"Blink 182 - "Always"Collective Soul - "Shine"Elton John - "I'm Still Standing"Fall Out Boy - "A Little Less Sixteen Candles"Foster the People - "Pumped Up Kicks"Fun ft. Janelle Monae - "We Are Young"Great White - "Once Bitten, Twice Shy"Iron Maiden - "The Wicker Man"Kool & The Gang - "Jungle Boogie"Living Colour - "Cult of Personality"My Chemical Romance - "Sing"P!nk - "Raise Your Glass"Quiet Riot - "Metal Health (Bang Your Head)"Rick Springfield - "Jessie's Girl"Shinedown - "Diamond Eyes (Boom-Lay Boom-Lay Boom)"Tears for Fears - "Shout"Of course, those 19 songs (and whatever other ones Harmonix announces before the release date) will join any Rock Band downloadable tracks you already own as playable songs in Blitz. Likewise, you'll be able to play any of the above songs in Rock Band 3 as regular DLC. Hell, I'd pay $15 just for "Jungle Boogie" and "Jessie's Girl," but maybe that's just me.
