Radiohead puts back catalog on iTunes

First six albums appear Tuesday morning

NEW YORK -- Radiohead's back catalog suddenly became available for sale via Apple's iTunes Music Store on Tuesday morning in DRM-free files, removing it from the ever-dwindling list of major holdouts from the digital download service.

The band previously had a handful of songs on iTunes that were included on various soundtracks or compilations, and earlier this year, Radiohead's new album, "In Rainbows," was made available there.

But only Tuesday had the band's first six studio albums gone live. Radiohead had been holding out because of its desire for fans to buy the albums in complete form, rather than as individual tracks.

In September, U.K. retailer 7digital scored a coup when it added Radiohead album downloads to its service, but not individual tracks.

The Beatles, Garth Brooks and AC/DC are now the last superstar acts without a presence on iTunes.
