WASTE !
I hate robots, machines, djs with laptops...
I'm an old fashioned guy. I love vinyls (especially 7"), don't bother counting anything, not even the empty glasses on my side, and like it warm, real and live. In one word : HUMAN !
I don't think you need to count BPMs to keep it wild'n'kickin' ! And I believe that's the only thing Rock'n'Roll DJs need to be ! WILD'N'KICKIN' !!!
