Why are you so closed off to edm? Just because it wasn't made with a primitive instrument doesn't mean that it isn't good music.
I don't like how it sounds and I like the way instruments such as the guitar sounds. I just don't like something that sounds computerized, including vocals.
"if any"? are you kidding?
There are very few made by the Beatles that have to do with drugs, but I can name 2 off the top of my head:
Doctor Robert and
Got To Get You Into My Life.
As far as the Stones, I am not as interested in them as I am with the Beatles, but I am sure there are a couple.
The point is: instead trying to find which songs are about drugs, with rap, you are trying to find songs not about drugs.
