I’m not saying that there arnt ANY, but as a rule of thumb for the genre it is not normal. Same thing as there is usually no big DROP in techno tracks USUALLY but there are songs out there that are techno with progressive and electro influences.
Sure u can refer me to probably tons if not hundreds of tracks out there that are not governed by these genre guidelines…but I could also post a link to 2girls1cup…they both exist and are both out of the norm 🙂
I am speaking in general rule of thumb based on genre. Sure there are psy trance with glitch hop influences or electro house with Dubstep bridges and trip hop breakdowns…get my drift?
