I mean it's stupid to label an artist to one specific genre anyway. What kind of artists makes the same music over and over again? They can make music in vastly different styles and that's fine.
I don't feel that way. I can see that if we are talking about, sub sub genres and stuff to the point where more categorization becomes completely arbitrary but I don't think it's bad to differentiate between techno, dance, drum n bass, trance, hardcore, hardstyle, dubstep, house and trap. I mean like... if I ask someone to recommend me a great trance track and what they show me is hardstyle or trap, then this doesn't help at all.
And I love when people do experimentations and try to mix stuff from different styles, but labels don't hinder that. I like this track here a lot:
This is part dubstep, part trance (mostly up to 1:15) and I love it.
I can differentiate between something like dubstep, drum n bass, and house.
But House/Techno/Trance are all so similar to me. I believe its only the tempo that is largely the difference and trance can be more "epic" in scale if that makes sense.
I have no clue what hardcore/Hardstyle is. I think I have an idea of what trap is but its weird to put Big Wild and Troyboi in the same genre
