Correcting Artist, Album and Song Info In the Mac Music App
If you have songs in the Music app that are missing information then the app may not group them by artist or album correctly. You can correct this information easily in the app. You can also modify songs so they appear on the proper albums and sorted in the right order. You can add album artwork too, and set the order of tracks in an album. This works the same way before Catalina in the iTunes app and will even work for songs obtained from Apple Music and sync with your other devices.
