I've created a youtube playlist of select trance classics.  It currently has over 300 videos and the first 30 videos are in rough chronological order.  I plan to finish the chronological arrangement throughout the list.

If you enjoy trance, want some inspiration, want know more about it's past or just want some cool music to listen to, here you go.  All videos are the best quality I could find and none of them feature questionable artwork you might not want on the screen while you're at work.  If you have suggestions of your own let me know, if I like them I'll add them to the list!
