spice3D : I think it was said in different words, but don't worry :
You mean : if you are looking into a list of artists, you want to see a album art icon besides the name right (not the grid correct) ?

But genres? if we do that we need to pick a random album art? that maybe cannot say much about the genre? sorry but I really disagree of the use here.

Albums make sense, and they are already by album art, but maybe what we can implement in the future is the album art by artists. I think that is missing for sure.
