Rock 'n' roll music in the 2000s was a little like space junk: The debris of skyrocketing careers launched in the 1970s and 1980s continue to orbit the world of pop music, cluttering up the atmosphere for any new missions. The irony is that some of the old supergroups that refused to go quietly into the musical night made some of their best music in years during the decade-with-no-name. You just didn't hear it, because they're "classic rock" artists but "classic rock" radio can't play any songs from after 1985, or it might melt. In the last couple of years, R.E.M. and the B-52s actually released great albums, except their fans were all out working PTA bake sales, and the kids just don't understand. Here's R.E.M.'s non-hit single from 2008, "Supernatural Superserious."
