I would like to suggest a feature that it is already available in Clementine, but not here.
It is Album Artist scrobbling. If my song is tagged like Artist = 'Beatles' , Album='xxx', title = 'whatever..' and Album Artist = 'Various Artists", then the Album Artist field is not populated in Last.fm.
I have tried with option "Prefer album artist when sending scrobbles" both checked/unchecked but the result is the same.
In Clementine, Album Artist is scrobbled with this option unchecked.
thanks a lot!
