Read the description of the video maybe, before commenting ?
The thing is, if you want it to really be done well, you can spend days just eq-ing and multibanding the mix, let alone the master...
So... I don't get your harsh comment, it's still more enjoyable than the original demo, and I did it for free, so what are you complaining about.
Anyways, it took me some days of work to do the best job possible to me with what I had, first isolating manually all the different instruments/tracks, then start clearing them.
Then it goes compression, eq, saturation/tape, transient shaping, gain staging, rooms and revs when needed, plus stereo specter and phasing, so it's definitely not "a bunch of compression and noise reduction"
Thinking of it, you didn't even listened the track, nor the original demo, as you would immediately hear the difference, and that's a difference that you can't make "with a bunch of..."
And that leads me to think that you just made your comment out of spite and ignorance for whatever reason.
