There are dozens of fantastic fan-created remixes of Undertale's fantastic music, so why not put them in the game? This ever-expanding collection of symphonic remixes, rock covers and even sound effect tweaks will enhance your next Undertale playthrough with a simple copy/pasting of files.

Featuring 92+ unique files on the core package, and dozens more optional tracks that you can swap in at your leisure.

Featuring RichaadEB, StringGamerPlayer, DM Dokuro, Insanentherainmusic, Gooseworx, Nirre, Nick Oleksiak, LittleVMills, and more! I take absolutely no credit for any of the music, save for a few minutes of editing. Please leave a comment if you have feedback or suggestions. Keep it constructive and specific so I can effectively fix or improve this mod.

This mod is constantly being updated, so be sure to hit that Mod Watch button at the right so you know when the next update is out!

RECOMMENDED TOOL: There is a tool by the name of VelianDev that will automate the copying of the default files. Use this if you don't like copying files manually or reading manuals or something. Nexusmods.com?


Post V1.19 patches will now feature two separate downloads: one for the main mod, and one for optional Bonus Tracks. This is to cut down on file size for those who are fine with the "vanilla" version. While any files in the Bonus Tracks will technically still work without the main mod, it's highly recommended you have it anyway since many of the tracks in-game (usually minor ones) don't have any alternative tracks.

V1.2: Massive overhaul, just in time for Undertale anniversary (I wish...)! Added a variety of new tracks and cleaned up others (Some tracks were a bit loud!). Feel the sins prematurely crawling down your back at the neck of the forests, take a moment to enjoy the view of the Castle with Monster Kid at Waterfall, hear the cries of the fallen as you stare eye-to-eye with the abyss, and more!

Also features a voiceacting Easter Egg from Youtuber OverEnglishman! But will finding it be worth the price?

There's a ton of fantastic fanmade covers out there, and while only one for each song made the current in the main mod, I've taken the liberty of leaving...

I suggest this cover Youtube.com for the true lab instead, it's more subtle.

The ruins replacement is a .wav file instead of an .ogg

I don't suppose Undertale is set up to detect looping? At any rate, redownloading this for the music at least.

Well, I'll have to be honest - these alternate themes are good, but by comparison with the originals, I'm kind of cherry-picking the ones I like and mainly replacing the original versions. In some cases the remixes just aren't as good as the originals, or not quite appropriate.

I'm always worried that people won't find the songs thematically appropriate, even ignoring personal taste of certain genres (be thankful that I didn't give you a Death Metal version of Heartache XD).

Is there any chance you could be more specific, as in song by song? I'm planning on updating the build in a manner of days, so it would be good if you could help me out before then!

Which part are we talking about? I am aware that there's a VERY specific part of the song that I can't mod (in the transitioning scene after the stages where he savescums on you), but there shouldn't be flat-out silence in any part of his song.

i found the problem, the "mus_repeat_1" and "mus_repeat_2" files didn't had the "_" before the numbers

You might be using an older version of this mod: I think I recall this being an issue a while ago (Ah, yes, I remember, I found it while recording the showcase videos), but it's long since been patched.

I think I now understand why developers are much more strict in labeling their software builds and making sure customers are using the latest version XD Thanks anyway!
