Billboard has released the sales figures from the first week of the Beatles in the iTunes store: more than 450,000 albums and 2 million individual songs have been sold via iTunes worldwide.

The Beatles were one of the best-known holdouts whose music was not available on iTunes, and while the response from consumers may or may not be what it takes to convince AC/DC (and a few others) to make their music available, the sales figures were still eagerly watched. By comparison, sales of the Beatles' music far exceeded those of Led Zeppelin when its catalog came to iTunes in 2007. Led Zeppelin sold about 300,000 individual tracks in its first week in the iTunes store.

Yesterday, Apple teased visitors heading to its homepage at www.apple.com of a major announcement, coming this morning at 10 AM EST. "Tomorrow is just another day. That you'll never forget," the homepage text read. Initially, people were hoping that the news was related to the long-rumored "iTunes in the Cloud" service, which Apple has been building large data centers in N.C. to support, reportedly.

However, later in the day, a number of folks had figured it out: the news was that the Beatles were finally coming to iTunes. The WSJ confirmed. As it turns out, they were right.

Paul McCartney's whooping encouragement, Lennon's calm breaths and Harrison's pensive plucking - if you're a Fab Four fan, you already know that tomorrow marks the official launch of the Beatle's remastered catalogue. But to further fan the flames of excitement, Yoko Ono spilled the beans that the discography will also finally appear in the iTunes store. According to 9 to 5 Mac, Ono told Sky News that the entire Beatles back catalogue will be available for download in conjunction with tomorrow's Apple event. While the post has since been removed, Twitter has been a aflutter with rumors. The long awaited event will also happen with the release of The Beatles: Rockband.
