what I especially love about popular electronic dance music is the way you get these proliferations of subdivisions that only a tiny minority of metaphorically-beardy DJ geeks pretend to understand
so you have hard trance, psychedelic trance, goa trance, hard house, handbag house, progressive house, deep house, trance techno, techno trance, trancey trance and housey house
all of it representing a marathon of wanking to cover up the fact that most of it barely qualifies as actual "music" in a huge sloping mound of jism
