Ever heard a song on TV and wished you could buy the song but just didn't know what the song title was? Well, Apple has debuted two new iTunes "features" that may help you out.

The first is "Commercial Success." There are currently 26 songs available for download and they come from commercials for various companies including Apple, Old Navy, Budweiser, Jaguar, AT&T, Cingular, Motorola, Dockers, Diet Coke, Candies, Honda, Hilton, Citibank, Nike and more.

Apple's other new "feature" is "As Heard On" which makes it easier for American Idol fans to download songs contestants performed on previous episodes. An interesting navigational feature here is the use of tabs which let you browse songs from "This Week," "Last Week," "Previous Weeks" and the "Complete Set."
