Where can I find the ingame music using SlumpEd?

[TailsMK4]

I need to know where in the pk3 is the music used for the game. I want to find the final boss's music to use for Roboenza. I know what the code is, but I do not know if I have to find a music lump and replace NOHOPE in the Roboenza wad with that lump, or if just replacing .ogg with the name of the music will work (likely not).

Sorry if it sounds difficult to understand, I'm not quite sure how to put it into words. Also, do not ask me to search (couldn't find my answer), or rip the music (pointless when I can just get it in MM8BDM itself).

EDIT: Nvm, I found out it was a wad file. I don't need help now.
