It's exactly that time!
Actually, all that I was going to say is that music is consumed differently now, and those who are the types that really would have been into the Stones in the past, now have a hundred indie bands to choose from instead of just the Beatles or The Stones to fight over. And because everybody's taste is a bit different, everybody gets their own band. That's part of indie's charm, and part of its curse. The shared culture of a giant band is missing, but you get to have this thing that is almost exactly to your taste, and shared with just a few people. A lot of bands today aren't in it to fill stadiums (though they probably wouldn't mind). They're happy with a small cult following.
I love the Stones but I don't know that we'll ever see anything like them, or Zeppelin, or The Beatles phenomenon again. Music consumption is different, music itself takes up less of a share of the cultural pie (video game franchises are the youth hits of today, and I don't say that with derision, its just something else to be into and they're very well done).
But yeah, I will say that you can't look at 2012 through the lens of 1972 and find anything like that. It ain't dead, its gone into hiding.
