As someone who was a teenager in the 60's and early 70's we had the best music era.
80's wasn't too bad before grunge, but a lot of grunge onward "music" is hard to listen to. I have most of the music from the bands you listed, but there's not a lot of talent out there. Mostly noise.
You have to remember, the record companies don't care what you listen to as long as they can make $$$ from it.
