This is a collection of the Undertale au songs made by amazing artists with more high quality, more original, and less loud themes using Sans's Leitmotif theme like "MEGALOVANIA" and "Song That Might Play When You Fight Sans" and many other themes that are pleasant to listen to!!
Some songs with the Sans leitmotif are still missing and will be replaced in the future maybe.  I might make this into a mod maybe who knows!
I will be using all the songs by other creators to create a mod for the Au of course and crediting them for it as well.
So ENJOY!!

face to face.

Varik, by bus, travels to a small town resting near the peak of Mt. Ebott. He has been called for one last job: to find and kill whatever is kidnapping the children residing in the town. Nothing he hasn't seen before, right?

One Last Job (CD)

this is based on this old weird flp edit i made https://www.youtube.com/watch?v=Y8_8pmGo1vU

i felt like updating that into a proper it's raining somewhere else styled once upon a time replacement. if this is for any au it's my one that's technically a storyspin take, but in reality i made it on my own as a reversed storyshift in 2016 before learning that was just what storyspin was. (does that mean im technically the creator of storyspin??? maybe???)

Deepertale is an AU that takes place in the aftermath of a nearly complete Genocide Run. Alphys has hidden all the survivors in the True Lab. Flowey was the only one who got in the human's way and lived to tell the tale (and that was by escaping within an inch of his life). The human has chosen not to erase the timeline yet, and walks the dusty Underground while down further below the monsters cower in fear. Sans takes the role of Flowey. How did he manage to get that kind of form if he was killed? Well...all will be explained in due time.
