Apple's homepage has been changed to promote the upcoming Pepsi-iTunes 100 million song promotion.

Apple also announced that five new Pepsi commercials for Pepsi and Sierra Mist will be aired during the 1st, 2nd and 3rd quarters in the Superbowl on February 1st. The five ads will be:

Pepsi iTunes – “I Fought The Law”
Pepsi – “Crossroads”
Pepsi – “Mountain Men”
Sierra Mist – “Bagpipes”
Sierra Mist – “Fire Escape”

Based on the descriptions, the "I Fought The Law" commercial (screenshots in comments thread) appears to be the only one directly promoting the Pepsi-iTunes promotion. This advertisement was previously described as featuring teens previously sued by the RIAA (Recording Industry Association of America) for illegal music downloads.
