I was listening to some oldies and it never occured to me how many artists probobly chain smoked while recording, the outcome sounds so diffrent sober than if you were listening to the same tracks high, like the way they mightve hit the drums or the way they wouldve hit a note, the passion was there and you can feel it as you groove with the song and it inspires you go make some music like wow the human mind is really amazing being able to be creative and make music.
An example has to be the x files theme song really thought about life in the universe and the purpose of mankind and space exploration lol
