It's a beautiful day if you love U2 and keeping your money (until you spend it on an iPhone).

Arguably the world's biggest band, U2 shocked everyone by announcing and releasing their new album, 'Songs of Innocence,' as a free download to anyone who uses iTunes, iTunes Radio or Beats Music. That's because the band unveiled the news at Apple's iPhone 6 event today (Sept. 9) in Cupertino, Calif., and the album will be exclusive to the company until Oct. 13.

Apple CEO Tim Cook called it "the largest album release of all time" during the event where nobody ever uses hyperbole. The band also performed the new song 'The Miracle (of Joey Ramone).'

The band previously partnered with Apple to release an official U2 iPod in 2004 in conjunction with the release of their iTunes box set, 'The Complete U2.' 'Songs of Innocence' is the first new album from U2 since 2009's 'No Line on the Horizon.'
