What are you trying to illustrate? Some sort of album view of each artist? I belive it's more or less available today. You can sort with album view today. Though you will not get the artist first and the album of that artist underneath. You'll get "Album name by Artist" on each album. If you had the Artist first, and then 20 albums of that artist, there might be confusion of wich artist you're really on after you've scrolled through 15 albums. A way of setting the context you're self would be really good though. I never use it because I can't get "Artist - Album name". It's just more logical for me.
