pretty much any pink floyd or phish song, also there is an echoes remix by orbital that that is really trancy and as well the usuall trippiness from echoes, i also like trance like oakenfold, i also like the real ambient stuff-aphex twin, -if you get npr, listen to hearts of space-comes on from 10pm-12pm only on sunday night-really trippy i have burned a couple works-each lasting roughly an hour-nothing but trippy space music for an hour-perfect for being stoned or on dxm or some opiate
