The number one gripe that I hate about the new music is “It doesn’t sound like the old music!!!”
This sentiment is patently absurd. While music is one of the most subjective art forms out there, and everyone is entitled to like what they like, none of the Halo albums have sounded the same. Griping that the new music doesnt sound like the “old” (read: Bungie) music is just wrong, because none of the OSTs sound like each other. CE was mysterious and almost spooky [A Walk in the Woods, Under Cover of Night], H2 was rock and roll [Mjolnir Edition, Breaking Benjamin], H3 was stereotypical “space opera music”[This is the Hour, Behold a Pale Horse], epic with long notes and high crescendos. ODST was haunting and filed with dread[Deference for Darkness, The Rookie], and Reach sounded almost tribal; appropriate for a “frontier” of space (I know reach was the biggest non-Earth population, but it wasn’t Earth, so we’re supposed to feel like it’s the untamed wild) [Overture, Winter Contingency].
Halo 4 took on its own feel, much like the previous ones, with a more technological sound (appropriate, since we’re dealing with the Forerunners, who are much more technologically advanced), mixed with some very emotional scores, as we get to see a much more human side of the Chief [Revival, Green and Blue, To Galaxy].
Halo 5 took the technological feel of the previous soundtrack and mixed it with some of the classic “Halo Theme”, due to our first contact with the “old” of Halo, Blue Team (also the name of what I think is the most beautiful song of any Halo game) [The Trials, Blue Team, Worldquake].
If you think I’m wrong, go back and listen to the full OSTs, and compare them. None of them sound the same.
I understand people not liking them because its not your style (because its music, and we could debate it all day and get nowhere since its so personal), but if you dislike it because its not “the same”, it’s just ridiculous.
P.S.: I personally enjoy all of the soundtracks, each on their own merits. If I had to put an order on it it’d be ODST, CE, Reach, 3, 4, 5, 2. But that’s just my opinion.
