No artwork with purchased music
When I purchase music I am not getting the album artwork with the song?
What is going on with Apple Music? So disappointing they can't get this right
I'm not sure what is going on. According to:
Add artwork to content in Music on Mac - Apple Support
Songs, albums, and music videos you buy from the iTunes Store or download from Apple Music come with artwork.
To retrieve album artwork from the iTunes Store for your entire library, choose File > Library > Get Album Artwork.
