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.
