I typically don't play this game with the music on. In fact, I haven't had it enabled in some time - in fact, when I heard comments on New Romulus about the music being good, my first reaction was 'This game has music?'
That said, excellent job on New Romulus and the Winter event! I actually keep the music turned on, which is saying something. I don't know if you have a new artist or simply have been feeding the old ones a better grade of musician chow, but either way, thank you!
