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

Okay...one more. 

“Mercury Blues” - David Lindley & El Rayo X

A kick in the pants and one of THE most absolutely effen raucous 4 minutes ever put down. 

Play it LOUD. 
Oh gawd yes, @oblgny! "Mercury Blues" absolutely smokes, and is a good recording ta boot (I've used it for years as material for speaker evaluations). I've seen Lindley perform it live with his great band El Rayo-X, and the room goes insane! People think The Who, The Ramones, The Pistols, and The Clash rock(ed), but none do harder than Lindley and his band on this song. The irony is that he is best known as a sideman for one of the laidback SoCal singer-songwriters, Jackson Browne of course. I've also seen David live with Ry Cooder, which is a real treat.

Yup - that cut is absolutely insane.  Even when I listen to it now it gets around 4-5 replays instantly.  I can only imagine what it would be like live. 

In the the same vein I’ll offer “Right Hand Man” by Joan Osborne.  Song just goes...
@oblgny, Joan is wonderful live, better than on record. Check out her live-in-studio version of Slim Harpo’s "Shake Your Hips" on You Tube. Very hot! Lou Ann Barton does a great version the song too, another great singer. She was Stevie Ray Vaughan's original singer in Austin, and now sometimes tours with his brother Jimmie.
Okay...anudder OBVIOUS one...

”Heartbreaker” - Led Zeppelin. 

That it’s also also one of the best rock riffs ever is beside the point. I read an article many years ago regarding the techniques used recording the tune. If my 60+ year old memory has retained anything, Page’s amplifier was situated 20 feet down a hall and cranked to eleven - or something like that. 

I swear that I can hear that.
