Comment 1 for bug 1348925

Thank you for taking the time to report this bug and helping to make Ubuntu better.

This is due to us currently using the thumbnailer to load the album art. We supply the artist and album of the track, then the thumbnailer service queries Last.fm for cover art.

I agree ideally we should use any cover art set in the file/folder primarily and fallback to using Last.fm. Mediascanner2 would probably have to supply the album art to us, I see there is already an 'art' property [0], but this would need investigating to see if it acts as expected.
