to be honest i do miss the gregorian chant or whatever you want to call it that were in the past halos but i thought i wouldn't like the new music....but now i kind of do. It's a new approach, new story arc, and a different look and feel to the halo series. We aren't just focusing on fighting covenant, killing flood, and destroying hula hoops in space anymore lol. 4 Years have passed and new technology has emerged and so there are going to be some changes like how mysteriously music always plays when you are in a firefight....never understood how that happened considering that never happens IRL lol.
