Cool song!
Cool song man! Indeed very vintage like you mentioned, using Fruityloops samples and such. It's not the kind of sound I personally would intent to go for, but sounds nice and addicting. Especially that lead synth you said you made in 3xOsc. I do however think you could have extended the build up a lot, and maybe added effects that would support the transitions into a more powerfull listening experience. Oh and the bassline definitely sounds too loud, it distracts me from the rest of this wonderfull song. Which I am sure; results in that empty feel people mentioned earlier. The bassline is like a background to a movie: If you make it too distracting people won't notice the foreground anymore. Lower the volume of the bassline and it will make the diversity of the song stand out again (:
