Knowing that will make you a good DJ, not doing the drop like everybody else or doing the transition that is going viral. An actual DJ is a musician, and uses whatever available to create its own version.
Here are the DJ's that I respect without a doubt.
Marc Acardipane
Hardcore pioneer, the man who brought the thunder in Thunderdome.
LTJ
Bukem
Drum and bass pioneer. Bukem is the one who showed the world intelligent drum and bass.
DJ Gabi
New talent. This Spanish girl knows how to do the tricks, live. Like a true DJ she creates tracks on the fly.
DJ ken Ik
Hear Mii, on the fly trying to keep the mood going. No actual playlist, just time for me in between tracks to come up with something.
