The main problem with all radio these days is the takeover by a few Massive corporations that dictate what we listen to. The golden days of radio seem to have died when MTV and Digital/Internet came along.
I don't think it's possible to ever regain what I grew up with, sure there was the "Must be Played list" of songs that the labels wanted promoted, but we also had independent legendary disc jockeys that had their own shows and could play whatever they found interesting, or you could request anything, even a 20 minute cut like Close to the Edge was possible.
I saw a program on PBS about the destruction of ground roots FM/AM radio in small towns across the US, they are gone forever and with them they take an intangible and irreplaceable part of our culture with them.
Okay that's my rant for the night.
