Looking forward to seeing what comes of Radiohead's radical take on selling their new album, In Rainbows. They are offering it first as download only, and the buyer can choose what to pay for it!! (you have to pay something, though).
Don't know what fans are paying, but they're sure buying: on the first day the album was available, fans shut down Radiohead.com in their mad rush to download it.
This has been hailed as a way to shake up the iTunes pricing structure, but I don't see how one band can do that. Nor could this approach help musicians who are not already millionaires, and thus able to stand the loss of revenue caused by underpricing.
