So what is Trap Music?

While looking for new music online i came across a song called Rollup by Flosstradamus (Baauer Remix). I saw that the tag for the genre was trap music, this got me curious. It wasn’t the first time i heard someone call their song trap music, at first i didn’t give it too much thought, for me it was like hip hop with some dubstep, but it seems more and more artist are creating what they call trap music. For more info about this genre go to dubspot. Now for the music:
