U2 has released the video for the new song "Invisible" that is catching so much buzz.

This song raised $3 million in 36 hours for their charity after it debuted during a Super Bowl commercial on Feb. 2. And the video got more than half a million hits in a day after its release yesterday.

Whaddya think? U2 will be the first musical guest on the new "The Tonight Show With Jimmy Fallon" on Monday. Glad they're back!  They'll perform at the Oscars too.
