You aren't supposed to upload music that's not yours on Newgrounds.
It's good, however I suggest you get to different beats a bit faster. I used to be like this where I would have the same loop a bit too long and I recommend spicing it up a bit with the melody, however, you're not far off from something great!
Thanks for the review dude!
Very nice drop, great buildup, and the feel is amazing
