In Rainbows, has become available for download

The band have let fans decide what to pay for the 10 MP3 files - from nothing to £100.

But they have refused to reveal how many people have ordered the album, or what they paid.

However, the Oxford-based band have scored number one positions for their last three studio albums - Kid A, Amnesiac and Hail To The Thief.
