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

I couldn’t possibly choose a best, so I’ll just offer one that I think deserves to be in the company of all the aforementioned greats.

Lynyrd Skynyrd - Free Bird
While I will always choose Gimme Shelter, or Sweet Home Alabama as my favorites, I think Twist and Shout probably best meets your definition. And I don't even care that much for The Beatles so go figure.

I did not see LA Woman either. Not a lot of Doors fans I guess
