Confirming rumors that have swirled since earlier this month, U2 has revealed that its new single "Invisible" will be aired in a world premiere on February 2 in an ad during the Super Bowl Final. The track is from the band's forthcoming album, due for release this spring.

The track will be played in an ad for Bono's (RED) charity, which aims to support the fight against HIV/AIDS and other diseases. "Invisible" will be available for free download on iTunes for 24 hours from next February 2, and Bank of America will donate one dollar to the charity for each download.

The members of U2 have kept something of a low profile since the release of their previous album, "No Line on the Horizon," in 2009. Fans have been awaiting the next U2 album, produced by Danger Mouse, since 2011.

Postponed several times, this 13th studio album is expected to have similar undertones to "Achtung Baby," according to the band's producer Daniel Lanois. Initially titled "Song of Ascent," then "10 Reasons to Exist," the album is scheduled to arrive in stores this spring.
