Well, it’s hardly a surprise, is it? All You Need Is Love was chosen as an Xbox 360 exclusive for The Beatles: Rock Band – meaning only owners of that console would be able to play it in the game. However, they’d have to buy and download it, with proceeds going to charity. Microsoft says in just two days it became the fastest-selling track in Rock Band’s history, generating tens of thousands of dollars for Medicins sans Frontieres. Meanwhile, a limited-edition Beatles-branded Xbox 360 sold at auction for $17,300.
