Hey Hippie,
You are saying that you should play music you like. While I don’t advocate playing music you don’t like (it pays to make yourself like a very broad range of music though!), playing only what you like is not a good plan.
Unless you are booked indeed as an artist and expected to play your genre, in which case you are definitely expected to play just that.
Reality is that most DJs will play in environments where there isn’t a very narrow music bandwith (i.e. single genre clubs for example) and it gets even worse if you go to more generic places where the DJ is not what people come for. He is just the guy there to make the night enjoyable as far as the music is concerned.
I’d say you can play about 20% the tracks that you really dig and use them to “educate” the crowd and/or introduce them to new or particular tracks. It’s part of being a DJ. It also means, imho, that 80% of the time you need to be playing what THEY like.
If a DJ expects to be one of those DJs that can suffice by staying within their narrow “what I like to play” bandwidth, you will most likely find yourself without many bookings and interesting only to a handful of places.
