I have a lot of music most of which is video game soundtracks and rips. I have tagged most of it using VGMdb years ago but most tools have poor or no support for it now. MusicBrainz is missing far too many albums and usually prioritizes translated track titles. It also lacks the huge amount of images for albums that VGMdb has
