For one day only, U2 is giving away its latest song for free on iTunes. Invisible was featured in a Super Bowl commercial that also welcomed Bank of America to the Red HIV/AIDS charity — a cause close to Bonos heart. For every download of the track, Bank of America will donate $1 to Red and the fight against AIDS. U2s next album — the bands first since 2009s No Line on The Horizon — is expected to see release this spring.
