Is Forces owned by Hirasawa which is why it was omitted from the vinyl?
Considering Hirasawa composed the entire soundtrack
it's odd that Forces was left out at all, but perhaps, since Forces is a recomposition of one of his previous works, Hirasawa may have soul ownership of Forces
the incidental music is owned by Hakusensha (or , again, whoever has the license that allowed the vinyl pressing).
