I don't think that Marty would stoop so low as to put this so-call genre of "Dub-Step" in Destiny. I have faith that he will do an as amazing job as he did in the Halo games. Perhaps even more so. And Bungie will probably support whatever music decisions he puts out there. Besides, if Marty did do some dub-step in Destiny, he of all people could actually make it sound good.
