I actually miss those days of the early 1990s when you could tune in a rock station and get a lot of great music from bands like Smashing Pumpkins, Cranberries, Pearl Jam, Soundgarden and Stone Temple Pilots, to name just a few bands other than Nirvana that were putting out great rock music at that time.
Today it seems that 90% of the radio stations out there play rap, dance re-mixes and modern country which has little resemblance to real country music. You can find decent new rock music but you have to subscribe to Sirius/XM (stations like Spectrum, XU, Loft) or go online with Spotify or Pandora and build your own stations.
The music of REM on the other hand (Michael Stipe) just did not age well at all. Songs like "Orange Crush", "What's The Frequency Kenneth" and "Shiny Happy People" sound stupid today. I've wiped all remnants of REM from my iTunes and my music collection is the better for it.
You forgot Alice in Chains. They were the best of the Seattle bands and grudge metal bands, imo.
