Need assistance finding the music from these AMVs!

[HentaiConnoisseur]

Hey! New here!
Sorry if this is the wrong place, but I collect and practically hoard AMVs and I have recently started sorting and labeling them.
But finding some of the songs can be difficult.










Also, if you could help out name the animes that appear, that would be appreciated and I'll love you forever.

I feel like you'd have much more luck asking in the YouTube comment section or trying to message the creators.
