Not entirely sure what the implications of this but I find it fascinating that while people could get the music for free via download they chose to it. I'd be interested in the demographic. How many young people, say under 25, actually like Radiohead enough to download their album? The big news to me seems to be that a band that has been around for 15 years (Pablo Honey came out in 1993) and likely has a fan base largely made up of 30-40 year olds (initial fans likely being 15 to 25 when they first heard "Creep") still embraced a newer technology more significantly than expected. I can imagine the Jonas Brothers as a hit but not as much Radiohead.
For the record, I downloaded it from the website.
