I dunno man, a lot of the people I know who use pot aren't all of a sudden retarded, and neither am I.
Infected Mushroom? Well, I don't know, I've never been an expert musician, but many songs are psytrance.
Well, I don't know either, I never hear of any of those guys. Maybe they're more underground. I listen to the Armind, Mau5trap and Anjunabeats labels, so most of the producers I hear from are either Dutch, German or British.
Right now I'm listening at whomever Monstercat throws at me, and the Going Quantum podcasts, but everyday I discover something new
Tbh I dont give a shit about what label I just find tunes obviously I prioritize people like Nicky Romero or Alesso
