Haunting, droning, chilling, atmospheric, riveting.
I miss the music from the first trailer. It reminded me of the movie Drive. Especially of A Real Hero by College. The ending piano track is beautiful, especially after ending the Drifter's story. Play the game and you'll see what I mean :')
Not sure about my favorite track. They all are, since they're part of one whole story. But I just chose the ending piano track. I want to learn it tomorrow on piano myself. Shouldn't be too hard!
