The music that plays at 5 a.m. in “Animal Crossing: New Horizons” is beautiful. I’ve only heard it in-game once. Not because I’m some Fortune 500 freak who thinks waking up at the ass crack of dawn is the key to success, or because I woke up in the middle of the night and booted up the game because I couldn’t go to sleep. No. Because I had been playing “Animal Crossing” for about three hours through the dead of night, planning and landscaping and building a discount Versailles hedge maze on my island.
