It's just the very first part, Im just pretty sure it's not in the game as it is, however the rest of the noodles are in game

For clarity, is this just restoring the very first part of Mirage? The rest of the song is indeed available in vanilla.

Hmm, actually damn i didn't notice this, they totally changed how song defs work, just got the error myself, yeah i'll do it thanks a lot for bringing it up!

Do you suppose you can make that change on your end and update the mod so that I am not using a modified version of the mod?

oh damn, i mean it works for me as it is, but as long as your change does the job that's neat as well, there had probably been a code change with 1.5 that I'm not aware of as i had first initially made this mod for myself back in 1.4 but it does work for me, so that's odd.

I went in and manually changed the outer tags from <SongDefs></SongDefs> to <Defs></Defs> and that fixed the error.

Should be a simple fix.

@VitaKanien it seems to be a fairly common bug with most rimworld song mods from my research, i have no clue why it would hand out that error but my best suggestion is try to either reload the mod or ignore the error message if the song still plays at least (use music manager to determine if the song is in the table of playable songs)

I get this error:
