Give me some good Dance songs please.

Im going to my friend's house on Halloween and I am making a playlist for the party. I have quite a large collection of Dance/electronic music, I just don't think people will know most of the songs I have, so I wanted to add in some popular dance music. I already have David Guetta, what else should I include?

La roux "Bulletproof"

Two Door Cinema club "what you know"

Carlito - Who's that boy

One of the best dance songs ever.

Whatever's on:
