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.

Sunday's top 40 will not provide an answer, either. The band's website does not report sales to chart compilers.

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