Slate's worst ad song ever competiton has been neatly won by, well, the worst ever pairing of an ad with a song: Royal Carribbean Cruise Line's use of Iggy Pop's "Lust for Life". My jaw was certainly on the floor the first time I saw that ad. Can you get it "in the ear" on Royal Carribbean? Also nice, though:
"The NFL's use of Lou Reed's 'Perfect Day' in a Super Bowl ad for itself. The ad: A montage of home movies and official films shows fans enjoying the thrills of the sport with Reed's song about heroin and suicide playing in the background."
