Display track numbers on Music (iTunes?) 2020

In Music/iTunes you can choose columns in the Songs view. Most other views are not customisable, but should include track numbers if the data is filled in. You can add track numbers if needed using the Song Info dialog (Cmd+I). The Album view on iPhone should include track numbers. If you want to see the track numbers in a playlist view on your phone you would need to manually add them to the track names or use the script method I suggested previously.

Try This Tag That Tag. I've not tested it, but it looks like you should be able to use it to prepend or append the track number to the existing track title, which might help you out.
