Radiohead fans will be able to choose how much to pay for the band's next album, In Rainbows, which is available for download on 10 October.
Instead of listing a price for the music, the group's website simply states "it's up to you" - and then adds: "No really, it's up to you."
Fans can buy the download or a £40 "discbox", which includes two CDs, two records, plus artwork and booklets.
