Now that the Beatles have joined the Rock Band revolution, any remaining holdouts (fearing being called a “sellout”) have decided to join the party. Most notably, U2 now want some of that yummy video game cash. Bassist Adam Clayton claims the band were initially put off by the idea, as they “didn’t want to be caricatured,” but now, after “what The Beatles have done,” U2 “love the idea that that’s where people are getting music, and [they]’d love to be in that world.” Well, that world just got a little bigger and a lot more mobile.

EW reports that EA, MTV Games, and Harmonix are launching an iPhone app version of Rock Band next week that “will involve tapping four spots on the iPhone screen in time with guitar, bass, drum, and vocal parts.” Great.

So which bands have signed along the dotted line for virtual mobile jamming? Here’s a partial track list (via EW):

30 Seconds to Mars - “Attack”
AFI - “Girl’s Not Grey”
All-American Rejects - “Move Along”
Beastie Boys - “Sabotage”
Blink-182 - “All the Small Things”
Blondie - “Hanging on the Telephone”
Foo Fighters - “Learn to Fly”
Foo Fighters - “Everlong”
George Thorogood & the Destroyers - “Bad to the Bone”
Jethro Tull - “Hymn 43″
Joan Jett - “Bad Reputation”
Lynyrd Skynyrd - “Simple Man”
Motörhead - “Ace of Spades ‘08″
Pixies - “Debaser”
Presidents of the United States of America - “Ladybug”
Rise Against - “Give It All”
Silversun Pickups - “Lazy Eye”
Smashing Pumpkins, - “Cherub Rock”
Steve Miller Band - “Take the Money and Run”
The Go-Go’s - “We Got the Beat”

As you may recall from the pre-Swiftgate era, controversy erupted last week over Activision’s use of Kurt Cobain’s image in Guitar Hero 5. In that case, Cobain wasn’t here to chime in on the debate over whether forcing the Nirvana front man’s likeness to sing Bon Jovi songs Karaoke style was just or even legally sound. Now I’m not sure if they signed off on this, but more famed (though living) rockers are getting the music video game avatar treatment: Stooge Iggy Pop and the White Stripes’ Jack White.**

**A rep for LEGO Rock Band has informed us that, in fact, neither Jack or Meg White are represented in the game. The leaked image of White was apparently a fake. We regret the error and apologize.

As seen in the leaked image (via Jeuxvideo.fr) from upcoming game Lego Rock Band above, Iggy appears in his iconic shirtless, microphone stand-wielding state.

Lego Rock Band, featuring Pop and the White Stripes is due out in time for holiday season, while Twitter rants and public outrage should drop later this week. Meanwhile, watch Pop’s video game avatar sing “The Passenger” here or embedded below:
