According to the Loop, Apple's iTunes Store recently exceeded 5 millions Beatles songs and 1 million Beatles albums sold worldwide, in addition to two million albums sold on Nov'24th,since its debut.
"Abbey Road" is the current best-selling Beatles album in the U.S., while "Here Comes the Sun" is the currently best-selling Beatles song.
The pace of sales has diminished since the Beatles' catalog first came to iTunes, however. Apple and EMI announced a week after the Beatles' music was released on iTunes that 2 million songs and 450,000 albums had been purchased.
On Nov'16, Apple began selling all 13 of the Beatles' remastered studio albums with iTunes LPs, the two-volume "Past Masters" compilation and the classic "Red" and "Blue" collections.
