I'll be honest, there's something I don't like about big DJs: they play the same tracks over and over again. It's like they're a clubhouse promoting each other. And it's even worse given that I don't like quite a few of the big hits being played this year.
They're also fake, self-centered people who will flip on you to the cops the minute they get pinched with some drugs. My motto since 1998 has been: "never trust a DJ" <--you can use that too if you like.
