When R.E.M. were hot I was already too old for them. By then I was listening to NRBQ, John Hiatt, Ry Cooder, Tom Waits, Lucinda Williams, Los Lobos, Steve Earle, The Fabulous Thunderbirds, The Blasters, Marshall Crenshaw, Nick Lowe, etc. You know.....adult music. Better songwriters, singers, and musicians than the guys in R.E.M. IMO, of course.
While the music of those I mention still sounds fresh and current (timeless), R.E.M. sounds of it's time: dated. Again, IMO. I know a couple of older musicians who are still stuck in 1966, to whom the music of the 60's (particularly The damn Beatles) is the best ever made. Just as older people in the 1960's felt the same about the Big Bands of the 30's and 40's.
There is no reason to expect current young people to be able to relate to R.E.M. any more than fans of the Big Bands could relate to the new music of the 60's. Just as the fans of the Big Bands didn't get or like The Beatles, young people now have no obligation to like R.E.M. We had our time, it's now their's.
