with the originals the music flowed with the gameplay perfectly. it was perfectly composed to subtly change without making it seem like the music had been cut. obviously it faded in and out every now and then but otherwise... Halo 4 was just a bunch of shoddy loops, and when you died it would start from your checkpoint from the exact beginning of a certain song(Broadsword race) which destroyed it. I never realised just how important the flow of the music actually is...
