obviously it's only my opinion, but modern psytrance is awful. How can the same sound being repeated for hours on end with the occasional synth going up or down be bearable to anyone? Went to a psy festival earlier this year and the repetitive dun dun dun dun dun almost drove me to insanity... I really learnt to hate 4/4 that day.
However there is real merit in older psy like Holymen, actually creative and interesting. Beavis in the Maze is an insane track, parts of it are almost ego shattering without drugs.
I mainly listen to Psybient, but have a lot of Breakcore, raggacore, jungle, IDM, and general electronic ambient genres but not all of which are danceable. The most danceable act I've ever seen is Shpongle, without a doubt.
