EvanKai writes "To celebrate Grey Tuesday, Eminem sues Apple to show his support for hiphop and sampling. CBS MarketWatch is reporting that 'Rapper Eminem's music publisher is suing Apple Computer Inc., claiming the company used one of the hip-hop superstar's songs in a television advertisement without permission. Eight Mile Style filed the copyright infringement suit late last week against Apple, Viacom Inc., its MTV subsidiary and the TBWA/Chiat/Day advertising agency.' While the ad in question no longer appears, several similar ads can be found here. I can't believe Chiat Day failed to clear the use of these songs with Pink, Mariah Carey, and The Who... or whatever major label actually owns the rights."
