Iggy Pop: U2 disc is a 'veiled advert'

Iggy Pop says U2's latest album, 'Songs of Innocence', is a "veiled advert".

The Stooges vocalist says that although the album was made available to Apple's iTunes customers free of charge, it would be inaccurate to describe the contentious new album - which has stoked plenty of controversy in the music industry - as free.
