Mood Tag for Songs

Hi

I’ve purchased a plex pass. I created 2 libraries for music. One for albums and one for songs where I do not own the entire album but just single songs (hope it’s understandable).

The mood tag seems to work well for my albums, but for the library with the songs, the mood tag doesn’t get populated at all. Has anyone got an idea if this is “by design” or if I do something wrong?

Thanks for your help

Regards

Phil

Does Plex match the tunes correctly? Does it download the right artwork?
