Code review comment for lp:~vthompson/music-app/use-model-art-property

I was attempting to add support for recent (and was going to do so for playlists as well), however, I wasn't able to get recent to work using the model's art property when an album is being selected from the Music scope. I might try to get everything working in the next few days.

I reduced the urgency of doing this because the current support thumbnailing via the web seems to have greatly improved. Perhaps something changed on the server to remedy the issues of poor cover art?
