There are two types of patrons: The ones that frequent clubs that play what they want to hear and the ones that go to hear what the DJ is going to do that night. The latter being the ones that are true fans of that DJ. The former don't care who the DJ is just as long as they hear what they want. I'd rather be the DJ they come to see because I'M playing.
Also, at some point in the history of your "favorite song" that song was new and never heard before. Someone had to have the balls to play it the first time so that it could become your "favorite song.'
