I have a hard time understanding what this did, partially because the page load is so long at this point (so maybe server stress wasn't part of the execution).

I have a hard time understanding what this did, partially because the page load is so long at this point (so maybe server stress wasn't part of the execution). When I finally figured out that I was finding albums by album art color, I closed the window. I'm not sure why this is titled "great execution." There's nothing wrong with the execution, really--but it doesn't strike me as particularly excellent in any regard. All that said, it's useless to search by album color.
