I’ve always considered goa and psy to be the same thing. Apparently goa typically has a heavier/more pronounced bassline than psy but normally I can’t tell the difference.
The rest is just up to personal taste. You can’t say that something’s just bad. I imagine that the way you feel about goa is similar to how I feel about most rap music but that’s still just my personal take on it. There are many out there who feel the exact opposite that I do and consider all my favorites to be “bad.”
That’s interesting though that your work’s got a monthly goa party, I’d like to find one of those to see what it’s about.
