questions in LISA

I got another question,

What is everyone favourite piece of unused/scrapped LISA media, fangame or official?

I personally like the unused hallucination warden fight in bashful, and the unused broken heart remix from Hopeful

do i sell the joy or do i need it for something?

0:34 - 0:53 what is this soundtrack?
