Fanart not working…

Hi last time I dith a fresh kodi 16.1 install on my sd card (using LibreELEC image for my RaspBerry Pi2)
Add my movies and tv shows and that works great, but after adding my music collection and update the music library.
When playing music most off the time the right fanart don’t work, only with 3 albums I get the right fan art.
With the another albums I get a random fanart slideshow off those 3 working albums, I tryed using CD ART Manager and download all the fanarts.
But I don’t get to work :/
