I like music from all decades, but prefer the eighties stuff. What I will say though is that radio in the 80s seemed far more diverse, instead of just playing the top twenty infinitum. It seems radio now wants the listener to get sick of a song quickly so they can move onto the next one.
I just don't think you see records like Def Leppard's Hysteria's chart presence anymore... music is much more throwaway: get em in, get em to like it, and then tell em to like something else.
