its just a full orchestral version of music that they are putting all instruments rewritten on a single sheet music.
yeah it plays the same song, but its just a half ass illusion that 1 person can be playing it when it requires dozen+
i will never be impressed by fake music made with apps. its one thing to make some indie game tracks, or a single riff for your home published rap album;
its another to pretend to be skilled by putting 20 parts on a single sheet with some downloaded program.
