As cool as Hotline Miami 2's soundtrack was, I'd personally disqualify it since most of the songs are licensed.
Yet MGS V still won when every song I remember from it was licensed and it squandered its main theme in a terrible scene
Rock Band and guitar hero have been nominated here before. Think of it like curating, how well every song meshed with the game. HM2 did that amazingly.
