I don't know what I heard, which version, improved or original . . . but I'm with Bapu in that the basics are covered mix-wise. I don't think a re-polish is needed at all, mostly because those who will headbang to this don't want it too pretty, they aren't marveling at the separation of instruments with surgical eq techniques.
They want a heavy rage quotient and spittle in their face. You've got it - mission f%^&$#g accomplished.
cheerio,
