Madonna has released a new digital song aiming to raise awareness about environmental issues.
Titled "Hey You," the ballad doesn't specifically refer to saving the earth, instead choosing to speak of loving and saving each other.
Produced by Madonna and Pharrell Williams, "Hey You" hit the market May 16. The first one million downloads are free, and Microsoft will donate 25 cents per download to the Alliance For Climate Protection.
Madonna will perform the song July 7 at the London edition of Live Earth, a global environment-themed pop event.
Other shows will take place in New Jersey; Tokyo; Shanghai, China; Rio De Janeiro, Brazil; Sydney, Australia; Johannesburg, South Africa; Hamburg, Germany; and Istanbul, Turkey.
