A Little Perspective, Please
This is becoming a music thread, instead of a Mac thread, but so be it...
We need some big picture perspective here. I am in the "Beatles Demographic" (fifty-something), and (surprise, surprise) I buy on iTunes. But I own all of the Beatles LPs AND all of the CDs, so their iTunes availability is not a factor for me. But this is not about whether my generation will buy the Beatles on iTunes, or whether the current generation will buy them, or whether they are relevant, boring, revolutionary or overrated. It is about making money selling music.
The fact is that their catalog will be extraordinarily valuable for many decades to come. Like it or not, they are legends. Don't take my word on that - just read the history books. And legends sell. In case you haven't checked, Duke Ellington has been dead for 30 years, but but people are still buying his music (there are around 4000 of his titles on iTunes - lots of duplicates, but still...). Hank Williams died in 1953, and he is on iTunes (maybe a few hundred tracks). Arturo Toscanini died over 50 years ago, and there are 600 of his recordings on iTunes.
Some of those recordings date back to the late 1920's, and have been issued on '78's, reissued on 45s, reissued over and over on vinyl, and then on CD, and now on digital downloads, AND PEOPLE ARE STILL BUYING THEM. They may not sell like Fergie, but they make money, because record companies are not charities, and don't release things that don't make a profit. Having the catalog of a legend is like having gold. Every generation is a new opportunity to sell these artists' work to new audience, and they will spend at least some money on them because they are legends. And you don't have to mount a multi-million dollar promotional campaign with billboards, magazine articles, Letterman appearances, and SuperBowl audience shots to convince people that they are stars. The history books do that for them.
So the Beatles thing is about the future. If somebody is going to spend $0.99 on A Day In The Life in 2010, Apple wants them to spend it at the iTunes store.
And don't forget, this will also put iTunes and Apple in the headlines and polish the luster of the brand even further. That's worth a few bucks in itself.
