Greatest Rock & Roll Song - Ever

This is not an easy question to answer, but here goes:

Joe Walsh- Life's Been Good (lyrically it personifies the rock & roll live fast, die young mentality, not one of my favorites but the definition of the lifestyle is in there)
Kiss- Rock & Roll All Night LIVE (and this only applies to the live version; I do not like any Kiss music but this is quite possibly the greatest live music spectacle I've ever witnessed)
Red Hot Chili Peppers- My Friends (just simple and beautiful)
Nine Inch Nails- Hurt (feel the pain and sorrow; Johnny Cash did a great cover of this also and the Cash video is hauntingly perfect)
Pink Floyd- Hey You (hey you, out there on the road always doing what you're told....hits way too close to home to ever get away from those lyrics)
Lynyrd Skynyrd- Simple Man (listen daily)

I know I'm in a different generation with some of these, but everyone has their reasons and the music that speaks to them. How could anyone ever pick just one? I'm up to 23 gigs of music and I still find more I like every day.

P.S. thanks for reminding me of The Allman Brothers.
