Media_title in a local mp3 file

Hi, I have google devices (nest and mini) that I use as media_player.
When I open a playlists from youtube I can see the title of the songs, but if I play local mp3 files, I can’t see any title because the media_title attribute is missing.
Would it be possible to add the attribute to the file? so I can see the title and maybe even a cover image?

Does anyone know how to fix this problem?
I didn’t understand if the title and cover information resides in the file, or in the case of youtube and spotify it is present in the server that shares the song.

Did you find a solution yet? I’m also struggling with that issue.
