"Heartbass" is an Electro/Dubstep remix of "Heartache" from Undertale originally created by Arcien. The track will play during the battle with Endigo Skyborn on Pacifist and Neutral Routes, replacing "Guitarache". It was first revealed that this track would be used on December 22, 2016.
- Panda's reasoning for including this song in the OST is that there needs to be "bass to drop".
- *However, "Kittylovania V2" is also a Dubstep track.
