MP3Tag + MusicBrainz Picard. I use MP3Tag to set the ID3 tags and picard to move them into the folder structure I want.

It takes a couple hours to set everything up, but I can’t rely on Musicbrainz alone because my music has no metadata on Musicbrainz, so I set the tags myself.

Just so you know, after you “complete” the game and are returned to the main menu, there’s still a bit of content left, so be sure to continue your save. Though it’s pretty obvious, I still missed it until I started watching a video about the game and realized I wasn’t finished.

SIGNALIS plays similar to Silent Hill, but is more focused on story.

I also use Jellyfin. Before being able to set custom tag delimiters, you had to ensure your music artists and album artists ID3 tags were correct. I believe it used a ‘;’ to separate multiple artists. Now with custom delimiters you can set your own. You may be able to try and fix things by setting ‘feat.’ as a custom tag.

Ultimately, I would recommend just using mp3tag and spending a few minutes setting up an action that replaces ‘feat.’ with a delimiter, such as a ‘|’. Run it through your current library and you should be good.

I haven’t tried it, but Metadata Remote is a web-based metadata editor.

Personally, I use MP3Tag with custom actions to set the tags, and MusicBrainz Picard to move files. My music isn’t on MusicBrainz, so I do the tagging myself, which usually doesn’t require too much effort from me.
