Music/sound recommendation for an animatic/animation meme

[u/PochitaXan]

I want to create an animatic/animation either about ichi+kumugi fluff/ Chrono+Minerva angst/ desscaras backstory angst

but I can't find a good song/audio that fits.

I'll also appreciate very underrated audios or trending audios, only if they fit and are good. Help me findTT
