Best rock song of all times


Only one answer please.
Not the best written or the best musical complexity but the one that represents the rock.

My choice: Satisfaction - Rolling Stones

Reasons:
- first notes are like the 5th of Beethoven (when you hear those notes, everybody pumps up the volume)
- still very up to date
- a mix of rock and blues rock and Motown sound
- lyrics talks about disatisfaction of young people vs life, politics, money and women (even B Dylan like that song)
- music is very basic as a good rock song should be

Hmm, I feel like I should name another one...

You all should listen to this one.  Tons of energy, uniquely garbed lead singer, and guitars blazing.  Anyone remember, "She Sells Sanctuary"?  1985, believe it or not...
