That's not a shot against the Stones, but they've been making essentially the same music ever since Brian Jones left the band.
To be honest, I don't really see why people feel the need to consistently compare them to the Beatles and Dylan. The Stones are good, but a tad over-rated in that they're compared to two of the greatest artists of all time, when there were so many other bands around at that time worthy to be placed into the trinity of rock; Pink Floyd was starting (and honestly, I think they produced some of their best work from 1967-1972.. the pre-Dark Side years), the Grateful Dead were on a rampage, Hendrix and Joplin dominated, Steppenwolf maintains in being one of the best bands of the time but only receives acknowledge for "Born to be Wild" and "Magic Carpet Ride", and the Velvet Underground achieved a sound no one will ever match.
I just think it's weird that when people try to think of the "best" rock bands of all time, they ignore all of the great San Francisco bands of the 1960s. It's probably one of the best periods/scenes in rock... It defined an entire generation, and the basic parameters of rock music.
But I'm starting to go off on a wild tangent now.
