Yeah, that was my pick too - seemed like the most obvious call in the world, but I guess there's no accounting for taste. Before Satisfaction, there was rock 'n roll, rockabilly, country, blues, but that song defined ROCK. it was the first and still hasn't been topped in my opinion. It was actually recorded more like 53 years ago (May 10, 1965 - three days before my 6th birthday...). But, yeah, that's a pretty damn long time ago. And it still holds up - doesn't sound old or dated at all except in the sense that it's always been there...Satisfaction.
There isn't any doubt.
It totally defines what a "Rock" song should be along with what a "Rock" band should be.
This is the song that enabled Rock music.
Has all of the elements ... great riff, great lyrics, attitude ...
And, it was recorded ~55 years ago. Think about that, 55 friggin' years ago. Now listen to the original recording, preferably, really Loud and after imbibing copious amounts of your choice of libation(s).
