Comment 4 for bug 1607531

Okay, so in my experimenting, I accidentally discovered something - some of the albums that have "working" album artwork have the album artwork in the same folder with the filename "cover.jpg", whilst all of the albums that do not have working album artwork have the filename "album title.jpg"... From what I can see though, this is not consistent as a bit more digging around shows that some of the albums with "working" album artwork use the filename "album title.jpg".

I have attached an animation showing the file structure of a typical album (note the So Country 2014 is the album in which I renamed the album artwork to "cover.jpg" to experiment).

* So Country 2014 previously displayed no album artwork when it used the filename "So Country 2014.jpg", but after I changed the name to "cover.jpg" and restarted, it now works.
* So Country 2015 is displaying the incorrect album artwork from an external source and as you can see, uses the filename "So Country 2015.jpg".
* So Country 2016 is displaying the incorrect album artwork from an external source (interestingly, one that does not even remotely resemble it!) and as you can see, uses the filename "So Country 2016.jpg".
* So Fresh Dance is displaying the correct album artwork and as you can see, uses the filename "cover.jpg" (not sure why this is, as I use "album title.jpg" - maybe Rhythmbox changed the filename at some point?).

I also have other albums (not shown in the animation) that display the album artwork correctly and use the filename "album title.jpg".
