Well i noticed this right as it came out... 2 plays :D
I'm writing this as a go on:
The start could be improved... idk, the strings just didn't fit that well here.
The intro is MAGNIFICENT.
Not a giant fan of the buildup... it didn't seem like there was one :l
A different dubstep bass should have been used... not a fan of this one.
Everything after the drop was also really good.
I'll give credit where credit's due. 4 for you. :)
