The music is something that is (in the Halo series) as important as the weapons....maybe it's way more important. The Halo music was totally unique and totally epic. The soundtracks of the trilogy, odst AAND H: Wars have this originality and this specificness which is important for a Halo-game. Reach....ya Reach lost this uniqueness. The Reach-Soundtrack wasn't bad, but it wasn't Halo anymore...in my opinion.
I hope, that the soundtrack in H4 will be again as epic as the ones from the trilogy. I mean like Brothers in Arms, Unyielding, Earth City, (oh gawd) One Final Effort, Farthest Outpost or even Peril. I don't want a mainstream-soundtrack which sounds like Two Steps From Hell. Yeah those soundtrack are epic, but I want a Halo-Soundtrack!
What do you mean?
