i like rhythmbox a lot and it’s so great to use it as a music player but most of my music files don’t even have any metadata it’s just “song-name-author.opus” so it’s a lot for me which is why i would use vlc instead yea!!! but anyway ummm why does xfce or gnome use rhythmbox??
Probably because it’s long standing and fully featured. It’s been going since 2001 after all.
