Done my share - as you probably know come to think about it. What I've learned about drugs and music is that they can never make bad music good. Drugs won't make good music better either. They just change how you perceive it, and it can definitely be an interesting and fun experience. For a while.
Lots of drugs can numb you to the point where bad music starts to make more sense though. But that's not bad music getting better - that's YOU getting worse haha
Still makes me think of my fave joke:
What does a deadhead say when he runs out of dope?
