Music selection is key, no pun intended

To give some context, last week I went out to the club with a few buddies just to listen to some tunes and hear other dj's play, I mostly listen to and mix house and funk stuff,

Comes this main event guy after a girl and a guy who did an hour each before (they were alright), and he's fuc*ing killing it with the transitions, guy's scratching doing some crazy shit, but his song selection was just awful, guy was playing strictly mainstream stuff and stuff that was popular 10 years ago, mostly some corny shit, but to be fair he did kill it if you look at his technique,

But if I wasn't a bedroom dj, I would just notice that he plays shitty music, and would not care if the guy could mix or not..

So just keep that in mind, always try and expand your repertoire and strive to be better overall, also gotta put hours in and have fun :D
