Congrats on the big improvements in this update!
I still have to explore the new functionality fully but for now I have noticed one small thing - would it be possible to have the selectable option to show the album artist for the biography page? typically the artist is what you'd want to show but for certain types of music/albums it might be best to show album artist. for example i am listening to some classical (chopin) and i'd like to see a bio of chopin (album artist) instead of the pianist (artist) playing chopin? i guess in this case "composer" would work too, but album artist is a bit more universal.
I'll take a look and see if i can suggest any other improvements, but bravo with your progress!
