Apple on Tuesday made a long-anticipated announcement: an old disagreement had been settled and The Beatles were finally included in the iTunes library. Although the Fab Four broke up in 1970, their music has dominated iTunes sales since it was added just days ago.

At time of publication, "Here Comes the Sun" is the top Beatles song, charting at number 19 on the iTunes list. There are currently 55 Beatles songs in the Top 200 songs, which means the Beatlemania has infected more than a quarter of the list.

It's not just individual songs that have been popular, either. All 13 of the Beatles' studio albums were released on Tuesday in addition to a two-volume Past Masters set and the Red and Blue collections. Each of these is listed in Top 200 albums. Even the lowest album on the list, "Beatles for Sale," is still pretty popular at the 38th spot.

iTunes currently lists three Beatles albums on its top 10. Abbey Road is in the number five position, Sgt. Pepper's Lonely Hearts Club Band is number nine, and The Beatles 1967-1970 (The Blue Album) has grabbed the tenth spot.

"We're really excited to bring the Beatles' music to iTunes," former Beatle Paul McCartney said in a statement. "It's nice to see the songs we originally released on vinyl receive as much love in the digital world as they did the first time around."

Each song is $1.29, single albums are $12.99, and double albums are $19.99. There is also a box set available for $149, containing all 13 albums, Past Masters, and two films.

"Thanks to the Beatles and EMI, we are now realizing a dream we've had since we launched iTunes 10 years ago," Apple chief Steve Jobs said.

With strong sales in these early days, it seems that iTunes and the Beatles have come together quite nicely.
