Uh dude, Rukkus is definitely not a third party artist. Most of his fake came from NG and his account is definitely still here, including this song you’re remixing. You’re totally fine unless you remix one of his songs that remix some copyright song like bass down low or astronaut 13.
Right, onto the song then. So I like what you did with the first drop, turning the first two measures of the original’s intro melody into the counterpoint of the dubstep melody; I think that’s a super interesting direction to go. Unfortunately, I can’t say the same for the second drop. It was the best part of the original for a reason; it was catchy as hell, and here it just isn’t anymore for some reason. In addition, the original had “drop” over and over, which worked well, but hearing the original sounds with “1 2 3 4” doesn’t have the same effect. I can’t explain why I feel this way about that, maybe it’s the pitch of the voice, or the fact that it’s way louder since there’s more space between each dubstep note here. Also at 3:04 there’s a very random piccardy third chord that doesn’t fit at all. I can see what you were going for in the second drop, but at least to me, it doesn’t work as well as it did in the original. Regardless, good job, especially on that first half!
