The Beatles are finally coming to iTunes.

Apple is expected to announce today that the catalogue of world famous Liverpudlian foursome will be available for legal download for the first time.

Apple and record label EMI have been in negotiations years about getting the music online.

On Monday, Apple added a cryptic post to its website that said “tomorrow is just another day. That you’ll never forget” and displayed clocks showing a 3pm London announcement.

For many years The Beatles’ own music label Apple Corps was involved in a fierce trademark dispute with Steve Jobs’ Apple computer company. The case was eventually settled in 2007.

This year Sir Paul McCartney, one of the only two surviving Beatles, said part of the delay in achieving a deal could be due to EMI.

“I know iTunes would like to do it, so one day it’s going to happen, he said.” .

The Beatles catalogue has been a noticeable absence from the iTunes store, along with the likes of AC/DC, Metallica and Led Zeppelin. Solo music by the bands’ members is available, however.

Neilsen SoundScan reported The Beatles had sold more than 30 million albums in the past decade.

EMI has claimed as the band have world-wide sales of one billion albums, they are the top-selling band in music history.
