I installed the app, and then imported all my FLAC files from windows media player. I noticed that there is a function where I right click on an album and select "Search the internet for picture" from the drop down menu. It brings up cover art pictures. I select the picture, and now I have the cover art displayed with the album... Cool, I did this for a bout 15 albums that had previously been missing cover art pictures. I noticed that there was now a file full of songs by "unknown Artist". When I opened the file, I saw that the it was full of the first track from every album for which I had recently uploaded cover art. The Metadata for Track 1 had been deleted every time I searched the internet and uploaded a picture. I had to manually re-enter al the metadata to get all the track #1s to be added back to their respective albums. I can only imagine this is some kind of glitch and not an intentional feature.
