A few years ago, people always referred to the Beatles as the biggest holdouts in terms of releasing their music for sale as MP3s online (mainly iTunes). However, the Beatles finally came around in November of 2010. After that, people started putting together lists of who was left and AC/DC and Kid Rock seemed to top most of those lists. So it seems noteworthy that both have just caved. Kid Rock's new album is available on iTunes, with someone saying that he finally realized that he could "no longer ignore how much money he was leaving on the table." And, the latest is that AC/DC has come around as well. Of course, AC/DC wasn't just not selling downloadable tracks, but they seemed philosophically opposed to the whole concept based on some of their quotes:

"I know the Beatles have changed but we're going to carry on like that," guitarist Angus Young told Sky News in May 2011, after the Beatles had ended their own iTunes holdout. "For us it's the best way. We are a band who started off with albums and that's how we've always been."

Back in October 2008, the band were even more hardline. "Maybe I'm just being old-fashioned, but this iTunes, God bless 'em, it's going to kill music if they're not careful," singer Brian Johnson told Reuters.

"It's a...monster, this thing. It just worries me. And I'm sure they're just doing it all in the interest of making as much...cash as possible. Let's put it this way, it's certainly not for the... love, let's get that out of the way, right away."

Yup. But apparently they're finally realizing that maybe it helps to go where your fans are. A bit late.

Of course, looking at those quotes, they sound mighty familiar to what we're hearing these days about other services like Pandora and Spotify. Why is it that there's always a contingent of musicians who so want to hate the services that actually deliver a legal product to fans?
