My god what an answer!!! it was so long and I had a little difficult to understand all that you said, cause english it's not my language jej.
Well, for what I understood, first you talk about melodies, vocals, etc. That's not bad necessarlly, but we talk abaout
electronic music, so that kind of things are "extra"...I mean that the essence of this music is not melodies & vocals, but without excess could be good. This is not the case of this song of course, and the electronic sounds in my opinion could be more worked.
If you listened themes from Posadas that he made in the 90's, for example with the name of mc beto, or tracks like pi or acid pastis, you should see that this vynil is bad compared with the past, You like it? Ok no problem, but talking about electronic music and a producer like Posadas, this vynil isn't a very good model...I'm sorry, that's what I think, and I respect if you like this tracks. The things that somebody like are one thing, and quality another one

And finally say that this vynil for me is comercial..the way it sounds dance music is always comercial (more or less in some cases), and i don't see big differences between the principal track of the vynil and dance. The beat is harder, but the rest is the same.
PD: Comercial doesnt mean bad, but in this case I see other things that I have explained to say that it's not a good product. I't`s only my opinion, y respect your's

Bye
