I'm not sure what time it's at but I think I like the music in the early hours of the morning when villagers are just starting to wake up, it might be the 7am, 8am or 9am. I'm really not sure. It's a tie between those or the 1am music. The 1am music is really calming imo, but so is the music for early hours. I really don't like the music used for the afternoon segments of the game though, it's just something about the instruments used that doesn't feel very calming or relaxing to me. Tbh, I much prefer the music in older games, as I have a lot of favourites from older games but not in New leaf.
