Apple debuted a new iPod + iTunes ad tonight on television. The ad continues the silhouette dancer theme of Apple's long running iPod ads. The ad is featured on Apple's iTunes product page. (direct QuickTime link)

The television ad promotes a new album called Growing Pains by Mary J Blige. Growing Pains is available for pre-order on iTunes ahead of its December 18th released date. The individual song, Work That, is also available now as a single.
Apple's use of songs in their television advertisements has clearly shown to be a boost for artists. Lesser known artist, Feist, recently saw significant exposure after 1234 was used in the newest iPod nano tv ad.
