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

Wow, we're not gettin fooled here. But not enough Pink Floyd or Roger Waters being mentioned.
Tommy Bolin - Private Eyes - Post Toastee

As well as many of the above mentioned songs
Jperry,Good pick,I have the CD every song is good! My pick for best rock song,,,and there is so many great ones,would be ,Walk this Way,short ,to the point ,and rocks like crazy.One of the only songs that leaves me wanting more at the end of the song.
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.
