There are a number of different approaches that someone or the other might want to take when they decide to finally become some kind of a DJ once all has been said and is now out of the way. The reason behind this is that being a DJ is a lot like being any other kind of musician. You wouldn’t assume that a guitar player would only ever play rock music since they might play jazz, pop or even Western classical music and Hindustani classical music often incorporates guitar as well so it’s fairly likely that a guitar player might want to dabble in those things as well.
That said, a lot of people that work as DJs are trying to earn a living. This makes it more profitable for them to play the latest tunes. A customer that has hired a DJ service Detroit to come and keep their party as lively as possible would not want you to play your avantgarde atonal dubstep for them. Rather, they would prefer that you play nice, simple songs that everyone can end up dancing to and thereby create an environment that would keep everyone as energetic as they need to be to fully enjoy the party that they are at right now.
You can always save your more artistic tunes for later. Since you are at a gig that is supposed to give you a way to pay the rent at the end of the month, figuring out how to make the most of this is essential and if you play all of the right tunes you might just be getting a number of excellent tips as well that would further increase your pay day.
