Same artist (say, "John Doe") appearing on J and on D, in alphabetical order.

[rodrigo1406]

I have a few songs from Al Green. One from the Pulp Fiction album, others from the Let's Stay Together album. The former appears under Al Green in "A" (view 1), the latter under Al Green in "G". All of them have the same "Al Green" in the "Artist" tag from the mp3. The same happens with, for instance, Elton John, which appears with some songs under "E", and other songs under "J".

I've filled a StackExchange question about it: https://unix.stackexchange.com/q/573692/134202

The surprising one probably has a "sort artist" tag. Try examining the files with Kid3.

What is the output of id3info <filename> for the files?
