Radiohead's seventh studio album was initially only available as a download from inrainbows.com for as much as one wished to pay (from free to £99). A credit card fee of £0.45 if you chose to pay any amount. The download area closed down on December 10th, 2007.
A personalized link to the album was emailed to you after your purchase of either the stand-alone digital album or the discbox (available at the fixed price of £40). The digital album came as a 48.4MB zip file containing 10 x 160kbps DRM-free MP3s, encoded with LAME version 3.93. No album art was contained in the ZIP file.
Along with the typical Artist Name, Track Title, Album Title, Date and Track Number fields, the ID3 tag included a Copyright and ISRC tag. Copyright was listed as _XURBIA_XENDLESS LIMITED. ISRC was listed as GB-STK-07-000## (where ## is the track number, 01 through 10).
The download was hosted by W.A.S.T.E., the official Radiohead fanclub. Purchases were handled by _Xurbia_Xendless, the secure server owned by W.A.S.T.E.
