I think pretty much all of the above will be listened to in 50 years (not popular, but listened to), however 200 years from now will be a different story. Popular music will be significantly different and the only ones to survive (other than the Classics) will be the same names in the history books. Beatles, Elvis Presley, and a couple of wild cards. Those two are not my favourite bands incidentally, I'm just being realistic about what's going to happen. Music is as fluid as language, constantly changing, a chaotic social maelstrom, and all humans have a bias to the music they were exposed to between the ages of 13-30. Everything else sounds like rubbish.
In 200 years people will look back on our popular music the same way we look back on Impressionist paintings. Historically important, not without their charms, but totally irrelevant and paling in comparison with whatever is happening currently, i.e. "What was great when I was a teenager/twenty-something."
And this is all supposing we're not about to die in a nuclear war and go back to knocking rocks together to get the party started.
