So what are your personal standout tracks from the UNDERTALE soundtrack? Not necessarily your overall favorites, but the ones that left an impression on you in some way. I could listen to Waterfall for hours, but I keep coming back to Another Medium, too.
Your Worst Nightmare
Perfect amount of madness and callbacks to flowey's theme, fitting the boss to a T. What makes it so great for me though is that rise that happens once you awaken all the souls, then proceed to retaliate against him. Gave me chills when I first played it.
Outside of that, probably either Snowdin, Undertale, or Reunited.
