“Hey You” is a new Madonna song, which sounds distinctly Christmas-y — surprising, since it was produced by Pharrell. But whatever, and we’ll save lap dance puns for the next time Madonna winds up at a strip club for research. It’s available online now to download for free, legally, as part of the promotion for Al Gore’s Live Earth bonanza, the seven-continent-concert that’s going to go down July 7th. Madge will perform “Hey You” as part of Live Earth, but don’t download the track just to memorize the lyrics. Get it now because for each of the first million downloads, MSN will donate 25 cents to the Alliance for Climate Protection. Nice work, Madonna.
