Come on now. I have never DJd before but how can any self-respecting DJ do a past 4am set and not drop a tune they found on 2trancental it is just unfathomable.
But replying to my own comment, I hope he/she/they realise by releasing every great tune on youtube, that granted no one has heard before. But should you hear these songs for the first time on the dancefloor of youtube. Maybe a lot of these producers wanted their music to be heard in a certain way. Not on youtube.
It's he lol true, though a lot of them do get played outside youtube as well :) and newer generations of djs and fans didn't have many other chances but hearing them here first.
