No worries! And thanks so much for clarifying :3 Sorry I wrote so much, haha. It's a bad habit >.<

I just really enjoy trying to make original music for my projects, so it seemed like a fun challenge to create a track that could be used in multiple ways since the track itself would technically be one music asset.

If altering it in-game with code is the only thing that's allowed though, I'm probably screwed on that front, haha. Like I said, I'm not a coder x3 That's pretty much why I use Naninovel to make my games in the first place. Cos I followed a Renpy tutorial in the past and the coding aspect of it was so headache-inducing that I knew I'd never want to make a full game that way. It just completely killed the fun >.<

I can try asking in Nani's support channel to see if anyone knows if it might be possible somehow though!
EDIT: I've been informed that while it's not possible with the bgm commands, there is a roundabout way to make it work to loop a short segment of a track specifically on a title screen, so that's cool ^-^
(the layering vocals idea will have to just be done in an updated/alternative version though cos I wanted to do x3 different versions, with a different phrase each time, not voiced by the voice actor but from sample packs that I own, haha, so that would be a no go cos it would take up too many words + count as separate voices I guess!)

But it's fiiiiiine :3 I was planning to probably make an updated or alternative version post-jam anyways because I tend to always try and have 2 voice actors + 2 sprites for 1 character in my projects just to give players a choice between having a masculine and a feminine voice and be more inclusive when it comes to romance. That would obviously go against the 1 voice actor rule, so I can always make a separate version that has the 2 voice actors + the stuff I wanted to do with splitting a music file :3

Even the updated version would still stick to the spirit of the jam since I wouldn't change the word count and the track would still technically be 1 track. Even the character would still be 1 character. It's just it'll look and sound different depending on the player's preference. I can just do what was suggested on the page and keep the pure jam version as a separate download for posterity!
