I agree
True.. A lot of 'psy' people ignore ambient music like Steve Roach, Brian Eno, Vidna Obmana,Biosphere, Matthew Florianz etc etc
And indeed ambient can be really trippy, especially artists such as the above mentioned, however I would also refer to certain IDMish electronica being very trippy in a braindance way (although a lot of tracks could probably work on the dancefloor if the listener is a bit familiar with it)
