Hi Dario, thanks for the follow-up! Well, I suspect there is essentially nothing we can do about this. dash.ubuntu.com almost certainly passes the request through to 7digital without tinkering with it, so I suspect what you have found is a problem in 7digital's API. It looks like it can handle the dots for artist art, but not for album art.
You can try this yourself: https://dash.ubuntu.com/musicproxy/v1/artist- art?artist=R.E.M.&album=&key=0f450aa882a6125ebcbfb3d7f7aa25bc This works. https://dash.ubuntu.com/musicproxy/v1/artist- art?artist=REM&album=&key=0f450aa882a6125ebcbfb3d7f7aa25bc This works too. https://dash.ubuntu.com/musicproxy/v1/album- art?artist=REM&album=Document&key=0f450aa882a6125ebcbfb3d7f7aa25bc This works. https://dash.ubuntu.com/musicproxy/v1/album- art?artist=R.E.M.&album=Document&key=0f450aa882a6125ebcbfb3d7f7aa25bc This fails. This proves that nothing on the thumbnailer side is responsible. It could be that dash.ubuntu.com is responsible for somehow mangling the artist ID in the cover art request (although it seems unlikely). I'll ask our dash.ubuntu.com guru and report back. Thanks for taking the time to let us know about this! ** Changed in: thumbnailer (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to thumbnailer in Ubuntu. https://bugs.launchpad.net/bugs/1559522 Title: Thumbnailer fails to fetch thumbnails from Internet Status in thumbnailer package in Ubuntu: Confirmed Bug description: I used Sound Juicer and ripperX to extract MP3s from my CDs. I copied my album to the phone, and I expected to see all album art in the Music scope and in the Music app, for every album in the phone. But, in some case Thumbnailer failed fetching album art from Internet (7Digital, I guess), and so Music scope is full of empty folders (see attachment).
