When you know what you like and what you want and you're able to nudge things in the right direction, that's more profitable than ever, because there's so much information out there. Everything's saturated. Tastemaker is probably the most overused word, but I still think it's important.
Traditionally, with a DJ set, you just go hear DJ that has a good reputation and let the DJ take you somewhere. It was up to the DJ what he wanted to play. Typically in dance music, people didn't know most of the songs a DJ played.
There's a lot of producers that are much more technical or gear-skilled than I am. But I have a pure idea of what I like and where I want to go and I follow that.
