yes i requested this option in clementine long time ago.

i ripped al my cd's and sacd's and remove all numbers i don't like, so i never have to skip/hear them again.
a lot of numbers get in folders with different artists albums, the cover.jpg/front.jpg will not work in one folder.
and it could be nice to scan for covers and embed them in the mp3/flac file

now if i scan and save a cover, strawberry uses this one as a albumcover for all files

OK, I'm answering to your comment after trying Quod Libet.
Quod Libet doesn't fit into my needs. These are the reasons.

It uses GTK and looks ugly in KDE. It doesn't support AlbumArtist tag and uses Artist tag in all places. I don't use Artist tag to maintain my collection (I use it only as information about featured artists, for example when guest rappers are on somebody's album). It doesn't recognize directory symlinks in chosen directory of music collection. I have separate directory for ripped CDs. Subdirectories of this directory are symlinked in my ~/Music/ directory. Quod Libet doesn't see these symlinks. It doesn't use breadcrumbs navigation and whole-window views (tiles or list) of nested resources defined by tags (like in navigational file manager), which was my expectation and was described in my first post.

The playlists are stored in SQL.
Reloading playlists from files will be a bit tricky to do. The other way, syncing playlists to disk would be easier and makes more sense.
An option for this could be added to the playlist settings. This needs to be done in the Playlist Backend: https://github.com/strawberrymusicplayer/strawberry/blob/master/src/playlist/playlistbackend.cpp
You can see how playlists are saved to file in the Playlist Manager here:
https://github.com/strawberrymusicplayer/strawberry/blob/master/src/playlist/playlistmanager.cpp

An easier solution would be that you just create a script that retrieves the playlists from SQL and saves to them to files.

To include new lyrics providers, it's added here:
https://github.com/strawberrymusicplayer/strawberry/blob/master/src/core/application.cpp#L68
and:
https://github.com/strawberrymusicplayer/strawberry/blob/master/src/core/application.cpp#L155

Then here: https://github.com/strawberrymusicplayer/strawberry/blob/master/src/CMakeLists.txt#L162
and here: https://github.com/strawberrymusicplayer/strawberry/blob/master/src/CMakeLists.txt#L378

+1 for this

please please support this

Thanks for the answer.
I'd shoulder it, but I have too many overtime projects right now. It is possible that in March I could deal with it or maybe in the meantime someone would be interested in this topic.

That looks great, especially since you can use Maloja as a proxy to forward scrobblings to other services too. I vote for supporting it!
