Agony just oozes 90s punk rock energy. She's boisterous and rude, taking breaks from her smoking habit to cuss people out.

Thesis definitely has to be something with traditional instruments. He acts like a stuffy old man (which he is) but he also has an edge to him, and and the kind of miserable old b*stard energy to fit a Nigel Burch song.

Duenna needs something grandiose and sweeping, but also powerful, she doesn't back down (for better or worse.) Also, she gets a villain song because she's not exactly done baking yet development-wise

Motif is, out of all of them the most silly and quippy, fitting a comedy song, but he also satirizes and jabs at himself in the same way that a this kind of song jabs at the topic being parodied.

Sequel is pretty broken. He's entirely wrapped up in his own past, which resembles the song and fits the epic quality to it, it's an epic to him. Also, songs about the movie industry!
