VGChartz’s Taneli Palola: “I’ve talked about it a few times before in these articles, but it bears repeating: music in video game can serve practically any role or purpose imaginable, from building tension for the appearance of a villain to creating a sense of calm and serenity for a place of safety, and to any number of other functions in a myriad of difference situations and games.
When you add lyrics to these songs this rings perhaps even more true, as they add an entirely new element on top of the instruments, and can expand on whatever the original intent of the piece was. These following tracks are played in a wide variety of different settings and situations, each meant to evoke a very specific emotion in the player, and they all do it exceptionally well.”
