Ah, the joys of ignorance and self-loathing!
It's a shame that tuppeny-ha'penny iconoclasm has no market value. Otherwise Fuckoff Island would be full of millionaires, instead of embittered, negative wage-slaves.
Here's the thing. Any record you hear on the radio bears audible traces of three crucial musical forebears: The Beatles, James Brown and Kraftwerk.
The Beatles are a musical and social phenomenon. De gustibus and all that, it remains that they changed music, the record business and British society.
They also realigned the UK with respect to the rest of the world. If they had come from another country they would be viewed with pride and affection.
However, pride and affection aren't cool, are they?
It should also be noted that The Beatles incorporated Apple as an company not just as a record label but also as a technology company (although nothing came of it). So they could have strangled Apple at birth, but they didn't. IIRC the deal was that Apple Computer could use the name as long as they didn't do anything related to selling records.
So the reason that the Beatles catalogue wasn't with iTunes is because the remaining Beatles (or their representatives) were under the impression that they had been grossly betrayed.
That being so, the appearance of the Beatles music on iTunes should have coincided with Hell freezing over. So let's see whether it's real or not, shall we?
