Editing Songs in Apple Music Not Working

The problem was a matter of multiple tags in my mp3 files. After proceeding with File > Convert > Convert ID3 Tags... > None I was able to edit single mp3 songs and/or albums. The changes were saved successfully.

I did not do the second step File > Convert > Convert ID3 Tags... > v2.3 though. Is that absolutely necessary or can I leave the song file's tags at "none"? Don't understand the meaning of ID3 tags in Music (iTunes) and how they work.

Isn't there a way to convert all ID3 tags of my entire library of mp3 files, instead of going through each single file/album?

Thanks for your help!

I have read & write permissons on all files and folders in Music> iTunes >iTunes Music.

Despite that the 17 MP3 files (songs) of the concerned album I would like an artwork to all have id3 tag v2.3 (see attachement), it won't allow me to add a jpeg image (.jpg) of 221KB as an artwork to it. By the way: Music/iTunes can't find artwork for this album. That's why I want to add it manually.

Most of my songs in my library are MP3 files with tags. Others, like purchased songs, are AAC Music Files from the Music/iTunes Store.

Super helpful thank you. :-)

Furthermore, I noticed that some missing artwork of a song or an album can not be added when editing the song or an album. I get the artwork (saved jpeg file on my Mac) from the pictures folder, insert it, click on OK and when I go back to the song or the album, the inserted artwork is not there. It's just no being saved, even if I did the id tag procedure you recommended.

Any solution for this issue?

I just did. Unfortunatley, other images I added to other albums in iTunes back at the time when I converted my CDs to MP3, do not work either for that specific album. I am also having difficulties adding or changing album artwork for other albums in the Music app.

Some albums have the artwork displayed when I click on the album, but sometimes individual songs of that particular album do not display the album artwork. That's very strange, too. All songs should display the album artwork, if the album does right?

I have a folder in my Pictures folder called CD Covers. In there I have 658 album covers, mostly .jpg images. Most of them I added to my albums manually back at the time where "Get Album Artwork" was not yet available in iTunes, but also later. when importing MP3 songs from other sources.

There seems to be some major issues with the way Music (former iTunes) is handling the music collection. I hope Apple will be able to resolve these issues, so we all can have a clean library of music.
