MTV's Rock Band has been enjoying overwhelming success despite coming out well after Activision's hit music simulator Guitar Hero.  Since both established a firm place in the market, the two games have been competing over the same consumer demographic, resulting in a number of exclusive exclusive content from various musicians.

MTV and Harmonix recently put out an AC/DC Rock Band, countering the Guitar Hero's Aerosmith and Metallica releases.  Meanwhile, both studios were busily courting the trifecta that holds various rights to The Beatles' works -- Apple, Sony/ATV Music Publishing, and EMI Music Group. 

Well, the verdict is out, and MTV came out on top, backed by their past innovation with music and general business credibility. 

"Introducing the genius of The Beatles to a whole new generation of music lovers through original and inspired ways is extremely exciting to us at Apple Corps," said Jeff Jones, CEO of Apple Corps, "We are truly pleased to be working with the innovative forces at MTV and Harmonix as they embody our mutual passions for music and creativity."

Unfortunately for Rock Band fanatics, there won't be any Fab Four DLC because MTV is keeping The Beatles for a new game that's still in the works -- call it a trump card, if you will.  The project was conceived with input from Sir Paul McCartney, Ringo Star, Yoko Ono, and Olivia Harrison.

"The project is a fun idea which broadens the appeal of The Beatles and their music. I like people having the opportunity to get to know the music from the inside out," McCartney said.

Starr added, "The Beatles continue to evolve with the passing of time and how wonderful that The Beatles' legacy will find its natural progression into the 21st century through the computerized world we live in. Let the games commence."

The executives at MTV and Harmonix are, of course, tickled pink.
