As expected, Apple’s iTunes Music Store today began selling the U2 digital box set (US$149.99) and the band’s new album, How To Dismantle An Atomic Bomb. The Complete U2 includes the band’s 15 official albums and over 25 rare, previously unreleased tracks, as well as a digital booklet (PDF) with band photos, album art and song lyrics. U2 fans can save US$50 on the digital box set if they’ve purchased the special edition U2 iPod.
