i havent decided yet whether there is just some really dope mastering work in that track (it was professionally mastered afterall), or if Paul's timestretching app is just extra-dope.  probably a combination of the two.  i dig the tune.

it was pretty much just put in the time stretching thing. the app is fun to play around with.. it's real easy to make theme music for a scary movie lol

my question though is, if i made a minimal techno track in fl studio today with no mastering and then stretched it with paul's app, would it sound anywhere near as good?

many unprofessional tracks in existance have "dead air" in them.  that is to say, between bass kicks 1, 2, 3, and 4, there's nothing. a void of sound. now stretch those 4 bass kicks out to 3 minutes in length and you're left with ~45 seconds timeslots of no sound.  as the basskicks come in, theyre abrupt and punchy, not smooth with a volume shift over the length of the kick, etc.  this is the process of mastering a track.  getting down to those kinds of details. when you start timestretching tracks (even in DJ'ing with applications like serato and ableton), those details in mastering start to show through (especially when the stretching algorithm is programmed well like in Paul's case). 

my thought process on this track is---it's not just "take any track, timestretch it, and it sounds like this."  i have a feeling putting any old track through a 800% slowdown is going to show the details of how well or poorly it was mastered.  is that to say justin beiber is some kind of musical genius because the details of his tracks sound good?  of course not.  his tracks get sent to professional mastering houses just like all Pop music does.  those firms are where there real talent lay.
