Very nice.
Great loop Mack! The beat was amazing and the synth was well placed, though a few REALLY loud bass noises would've put the icing on the cake. If this were a normal audio track and not a loop you'd have a ten BUT because it IS a loop, the song did not loop over well for the 2 seconds of silence from 1:20-1:22. If you ever consider putting revisions into this that's all I could imagine would need revising.
I'm impressed,
