U2 is going to debut a new song during Super Bowl 48 and then you'll be able to get it for free after that but only for a limited time.

It's not just the game that has everyone watching the Super Bowl.  The commercials get plenty of attention too.  Keep an eye out, or maybe an ear ready for U2's new song "Invisible" which will debut in a commercial during the big game.

After that, according to USA Today, the song will be available for 24 hours afterward as a free ITunes download.  Bank of America is going to donate $1 for each download to the Global Fund to fight AIDS, TB and Malaria, up to two million dollars.

U2's new album is expected to be out this spring.  They'll be Jimmy Fallon's first musical guest on February 17th on "The Tonight Show."

Pretty cool, huh and what a smart move too.  They'll have a global audience during the Super Bowl.
