another best trance song of all time is:

chicane-offshore or saltwater. true classic.
lost tribe-gamemaster(original mix)

I honestly am not as impressed with a lot of the new stuff quite as much as the old

Happiness Happening always made me feel like I was somewhere someplace beautiful and at peace (You all know what I mean)
Push - Universal Nation was a stunner
Carte Blance was really great 2
Children was and STILL IS fantastic. I'd say it defined Trance music.
Toca me (the original) isn't bad at all either
BUT the song that will always overwhelm me EVERY time i hear it is For an Angel by the master PVD. That song just puts me into......well a trance everytime they play it at a club. I can't stand some of the remixes of it with vocals (BLEH!!)

ahh push - universal nation...yum....and airscape - l'esperenza (avb mix) wow...what a great remix by armin. sweetness. there are lots of greats....these two stand out in my mind.

TAUCHER-CHILD OF THE UNIVERSE

DJ SAKIN & FRIENDS- PROTECT YOUR MIND(LANGE RMX)
