During the most hallowed of times for commercials to air, U2 will unveil a new song during a commercial for Bank Of America as both have teamed up with the (RED) Campaign.

The song, entitled "Invisible" will be available for free through an iTunes download for a full 24 hours after the airing of the commercial.

As an added bonus, every download of the song means that Bank Of America will donate a dollar to the Global Fund to Fight AIDS.

Be sure to tune in on Super Bowl Sunday to see the commercial and go get your free download.
