This article cites two important things pertaining to the Fab Five signing on with iTunes.
1. They just settled a dispute with their label, EMI, which is supposedly the last hurdle to them making the jump to the online realm of music distribution.
2. Who cares? Does anyone not have a Beatles album who wants one? Are The Beatles going to get a larger fan base because someone perusing the iTunes Store might say, "Huh. I've always heard of The Beatles and now that I can buy their songs for a buck each, I might give them a try"?
The Beatles on iTunes? Whoop-de-freakin'-do.
