Supernatural: 20 Greatest Music Moments

12. "Eye Of The Tiger" By Survivor (4.6, "Yellow Fever")

In "Yellow Fever," Dean--who is still traumatized by his stint in Hell--is infected by a fear-inducing illness that ultimately results in victims being frightened to death. As the symptoms begin to appear and Dean begins to grow anxious, he lies down in the Impala and blasts "Eye of the Tiger" to pump himself up as he waits for Sam to return. Really, who wouldn't? But that's not why Supernatural fans love this scene. The reason that this scene has become immortal is because of the blooper that it spawned. Shown as a clip at the end of the episode, we see Jared Padalecki deliberately miss his cue. Awesomely, Jensen Ackles just pops up and lip-syncs along with the song, throwing himself into the "Eye of the Tiger" spirit and not cracking a smile until the music finally cuts off. Jared Padalecki giggles in the background through the whole thing, and it's fairly hilarious. Watch Jensen Ackles Perform "Eye of the Tiger": http://www.youtube.com/watch?v=XTsxF47wx5M

11. "A Well Respected Man" By The Kinks (4.17, "It's A Terrible Life")

In this Season 4 episode, the format is a little...different. We open as an alarm blares at 6AM, and--although we immediately see Dean--the scene is all wrong. To the tunes of "A Well Respected Man," he wakes in what is clearly a well-organized and expensive apartment rather than a dingy motel room. Sam is nowhere to be seen, and everything is very shiny. As the scene progresses, we see that this Dean has gone corporate, complete with espresso machine, palm pilot, sushi, and NPR. His hair is carefully combed, his suspenders are snappy, his tie is straight, and his Gordon Gekko shirt is perfectly pressed. He drives a sedan and dislikes classic rock. He is Dean Smith, Director of Sales & Marketing. It's all very respectable, and very alarming.
