I thought the move toward direct distribution with users setting the price was genius. They simultaneously told the recording industry to shove it while connecting more directly with fans. I wish every band was willing to take such a risk.
I don't see why they wouldn't repeat it. Whenever their next album comes out, it'll leak, everyone who is a fan will steal it and then pay for it on CD. If anything, they're just getting extra money from people who love radiohead and will pay for it regardless.
"I think it was a one-off response to a particular situation." - Thom Yorke, frontman for Radiohead, saying the experiment with letting fans pay what they want for downloading the band's 2007 album In Rainbows would not be repeated.
