The one going on loop in my ears, right now, because I'm apparently incapable of listening to different songs one after another. It's "Remains" by the Aviators--inspiration for one of my most recent roleplay ideas.
I just finished listening to the Horizon: Zero Dawn soundtrack or at least half of it. It's four hours long. It sounds just as good as it did when I played the game which was amazing. I've been listening to more and more soundtracks, especially from video games. Even when I'm not actively listening, it's just nice to have in the background.
