Continuing the current practice of using YouTube as a proxy for actual content, I present to you the following: More obscure (more or less) songs in advertisements.

1) I'm sure you've seen those creepy Cadillac ads that ask if you and your car are engaged in a sexual relationship. Well, that commercial uses just a few seconds of a song called "Stars" by the band Hum. This song was hot in Chicago in 1995. Here's the video.

2) This Target Ad features a song called "We Just Won't Be Defeated" by The Go! Team. Here's a video of The Go! Team performing that song live.

3) Finally, another ad you're sure to have seen numerous times. The commercial for Apple's iPod nano: "A little video for everyone." Until last week I had never seen the entire video that's displayed on the iPod. So, here is "1234" by Feist.
