Their editor is such a nice thing to use. I add a lot of stuff weekly to MusicBrainz, and especially the media editor where you just paste the tracks somehow parsed, and it will create the media with the track numbers, names, lengths and artists. If you do this often enough, you appreciate the efficiency.

MusicBrainz/beets/flac/plex is my choice for music and it beats Spotify with the selection and quality.
