This playlist is filled with the very best (meaning the most well-made) Undertale Utau tracks I have found so far.  I look for new tracks to add fairly often, but I know that I have probably been missing out on a lot of good ones.  Feel free to message me about any that you think I should see; I may consider adding them to the list.  :)

I tried ordering the songs by character so it would be easier for you to "track" down whichever track you want.  Hopefully it helps a little.  Enjoy!  :)

not vocaloid wow

but yeah i really wanted to contribute something to the fandom, so have a heartwrenching song about frisk's (and not chara) thoughts while fighting sans

me? i love getting dunked on and do not regret anything

forgive my shitty mixmox

lyrics by the lovely @ateotu

I didn’t know what I got into
Somehow I can’t go back even if I really wanted to
So what more can I do?
Here at the end, it’s just me and you

I never wanted to play by all the rules
A knife in hand, I’m playing out the part of the fool

So here we go, you can judge me thoroughly
It’s too late for apologies.

Go ahead and just hit me since you’re able
We know my determination is unstable
I’m not even mad because I keep on dying
But I don’t even know why I’m trying.

This isn’t what I want, yet it’s what I asked for
Curiosity over all my morals
I took away our perfect, happy ending
Resetting the world despite the warnings

Right now I’m made of LOVE ahh… of LOVE ahh…

I know who you are, you remember who I am
We knew that once in a timeline, we had grown to be good friends
And yet I killed your brother without giving him a chance
Every time you throw me down, I hope you kill me once again.

So go ahead and just hit me since you’re able
All the sin that I can feel is unbearable
If I could only hit you once it would be over
But the consequences last forever

The flowers are in bloom as the birds will tell
It’s a beautiful day to be burning in Hell
You gave me advice, I chose genocide,
But I know how to make it right.

I am made of LOVE ahh… but I’ll give up for you.

Because I adore Sans, it's safe to say I'll be writing remixes for quite a few songs from Undertale, if not the entire soundtrack. I took a bit more care with this song, as it's amazing and needed lots of attention to detail because it's Sans's theme. Hello there Undertale fandom, I think I'll stay a while :3

But the 42 hours invested was worth it for Sans ❤ OvO

I decided I’d do a thing.

Very special thanks to Kylee Henke for helping me with the harmony lines, and designing the album cover.

First uploaded song, and a Dual Audio mix of the following two tracks:

https://soundcloud.com/djsmell1/stronger-than-you-sans-parody-final

Headphones are basically needed for this to be comprehensible. One track plays in the right ear, and vice versa. They have been synced to each other.

Lyrics:
you’re king of the underworld and there i’ll be by your side
we were humble subjects yet by fate you were led to rule
in order to protect you from everything that will hurt
i will sin and i will kill, i’ll sacrifice my all

fell to this world was a human child with a strong soul
with their sudden appearance here dust was clouding the air
but whether by will or whim the child passed and spared you
then the six human souls vanished along with our ruler

as the current king, you were gravely burdened
with the expectation to take all human souls
but i’ll never let you agonize on this
so you’ll smile and feel happy and be at peace

you’re king of the underworld and there i’ll be by your side
we were humble subjects yet by fate you were led to rule
in order to protect you from everything that will hurt
i will sin and i will kill, i’ll sacrifice my all

then one day i went to the ruins door by our town
there i saw a child in green and looking around in awe
with their shining heart of gold and tender friendly smile
i could only stand and stare, this small child had not one fault

but the people have one wish to be fulfilled
so the child must die even if their blood is spilled
i shall answer back to the wish that they hold
but then tell me why do these two hands shake so?

you’re king of the underworld and there i’ll be by your side
we were humble subjects yet by fate you were led to rule
“TODAY’S MEAL IS SPAGHETTI COOKED BY THE GREAT PAPYRUS!”
and you smile with no blame but soon it won’t be the same

the barrier broke with the seven souls i’ve obtained
though the humans found out and now chase us with much fury
if this is what they call retribution for my sins
i can’t have them take you down and burn along with me too

“i know it’s sudden and you were in the dark”
“but please trust me and run away with the others”
“it’s only till you’re gone that i’ll feel at ease”
“come on now, those expressions don’t fit you at all”

i’ll sacrifice my all so you can go on and be free
we were always together yet by fate now torn apart
calling us MONSTERS, i know of one person just like that
i have sinned, i’m to blame, ‘cause i’ve spilled innocent blood

once upon a time there were two most happy brothers
then that one human child came and there the story begins
after the child left one brother was chosen to reign
he was compassionate but then the world wasn’t as kind

as the monster king, you were gravely burdened (AND AT LAST, YOU’RE THERE AND I CAN’T UNDERSTAND)
with the expectation to take all human souls (AND THE BELLS RING, IS IT ‘CAUSE THEY KNOW IT’S THE END?)
but i never let you agonize on this (YOU DON’T EVEN BOTHER TO LOOK AT THE CROWD)
so you’d smile and feel happy and be at peace (YOU JUST WEAR THAT ONE PERMANENT SMILE OF YOURS)

[once this time line resets, if it ever comes to pass
let us share puzzles once more, and be best of friends]
