Ah. My first retarded impression was that Full-On was that kind of half-boring nothing changes type of psy, and Progressive being the fun and club-like music. But once you made an example with a group I actually know about (GMS), I kinda got the picture.
Seems most people here have since long ago advanced into the Psy-genre, far from the things I listen to. Or maybe not, I like a lot of dj's.
Btw, don't mean to bash on any progressive fans with this post or anything, it's just my taste in that sort of psy. I do, of course like some of those tracks. They're evil and plentiful.
