Hello again ^^
This post is about a very accidental cover I was doing with the program ModPlug Tracker.
Using the music "jingles_2.mod" by Lee Smith (all rights reserved to him):

The same music is also known as "tune6" in Amiga Music Preservation website:

Recently I was listening to the theme song titled "Gaster's Theme" in UnderTale, playing it via the program GoldWave, until I realized it matches with the rythm of the other tune mentioned above, if I modify the tempo.
In this video, you can listen to the result:
