Where/how to efficiently download music in bulk?

I have a relatively large collection of songs I downloaded from YouTube, one-by-one, on my Android phone. I would like to download a lot more of the songs I like, with correct metadata and without having to manually edit the album cover art, artist, and more, on my Windows PC.

(Notes: I'd be ok with running another tool that allows altering many files, like Musicbrainz Picard. Looking at https://rentry.co/FMHYAudio/#audio-ripping, it seems I might've answered my own question, but I'm unsure. Do you know of better methods?)
