I completely agree. For me, the music in every respectable Halo, and in Destiny, has always been a huge and irreplaceable part of the game, and I'm extremely disappointed to see Marty O’Donnell go. A huge part of any game is the music: if the gameplay is amazing but the music isn't very touching or emotional then I won't want to play it. Marty O’Donnell's music was just that - emotional. His music has always been extremely enjoyable to listen to, and since Halo I've always found that the music of other games doesn't have anything near the same profound impact on the experience of the game, or on me. I'm very sad that I'll no longer be able to enjoy his new works in some of my favourite games from what I once viewed as one of the best game developing companies on console (although that feeling lessened considerably after Halo Reach, but after much saltiness I was able to overlook that atrocity), and it's likely that I won't enjoy their future releases as much since one of the best things about their games is now gone. I hope that they can find someone half as good to make the music for their dlc, but an alien I remember very fondly says in my mind: "Were it so easy..."
