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

"Surprised that after 153 posts no one has yet mentioned "Light My Fire" by the Doors."

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

Ok, a tangent to this thread: Artists not yet mentioned:
Doors, Beach Boys, Aretha...
Afternoon Delight by Starland Vocal Band..............

Just kidding. How about Black Betty by Ram Jam?
I found this thread and felt it needed clarification. 
Rock is supposed to be hard as in when one find's
themselves between a rock and a hard place. 
Even Tina Turner sung about doing it rough sometimes...

Pure straight unadulterated rock is best described (imo)
by the song" Beyond The Wheel" by Sound Garden.
the album is titled "Ultramega OK". I saw them perform 
this album live in NYC when it was introduced. 
Kim Thayil (guitarist) did his single solo guitar work as in the album.
At the end of the show he leaned his Guild S-100 against
his Music Man full stack (tube, like Marshall) 
as the band left stage..... it rang out!!!!! Nice exit.
I don't think Herbie's Tube Damper's were employed.
That is Rock guys!!!!
