What Is The Song In The Apple 12 'Mmmmm, Purple' Commercial?

There are some songs you've heard so many times that the lyrics are embedded in your brain without you even knowing who the artist is. When an advertisement uses one of these songs, it can get stuck in your head for days. If you don't know who's singing, it can put you in a tailspin until you find it. Apple might have done this for a few people with their latest "Mmmmm, purple" commercial.
