This is a valid point. There's something about the composition of this that tells me there's something missing, it's not much more than the summation of the clips and bits that have been out for a while now. There is 2 minutes of this song missing and for the people who think that something missing 2/5ths of itself can't be changed by adding that 2/5 back I highly suggest cutting off both of your legs, trying to read just 3/5ths of a good poem, or some other equally stupid idea so that you can see the fallacy in your assertion. That said, the first part feels cohesive to me how it was done, but it seems obvious to me this version was mixed. I found myself surprised at how quickly it got started.
