My goal is to be able to listen to these songs again on Spotify.

Notable changes I made that happened recently in case they matter: I turned off “open Spotify on startup”, and I also switched my default browser from chrome to Opera GX and logged in my Spotify there. Apparently, opera gx’s Spotify doesn’t support local files and now the pc app (where this screenshot is from) is doing this. I don’t know if they’re significant to my problem but here they are in case they matter.

I also have a designated folder that all these songs are in. I just want to listen to my youtube exclusive music, man. I don’t care if I listen with ads between them, but at least help me bring back these songs.

Alternate solution: help me find a way to delete deleted songs so I could download them all again. See that shaded “Voices - Derivakat [Project Blade something” up there? That’s what happened when I deleted the mp3 file and I don’t know how to remove it. I don’t want that to happen.
