Wolf_garcia,
Probably best not to mention the lame parody. The parody is a parody because that image became over used and filtered down to the average. Lame is lame of course.
But musicians with vision and skills are a very different thing. The guys that learned their chops and put life experience into their performance is what I suspect left their mark on us. Not the navel gazers...
Sure the word "drugs" covers too many things. Acid, speed, coke, pot, ecstasy, and so on all effected the various specific musical movements of their time. It's a paradigm shift from what went before.
We could probably draw a simplistic table or flow chart. I.e
Ecstasy = Dance music
Speed = Punk etc etc.
