I can't answer how the Landlocked Blues song ended up with the Del Amitri PDF file, but that's definitely what is in the database stored in the cloud folder. If you want to send me a library backup file (Settings->Backup and Restore->Backup Library) of your Windows 10 library, I can try synchronizing to my own cloud folder and try to see if I can reproduce that, otherwise I won't know how your library ended up in that state, as I don't know what actions you might have taken, or what the database looks like on your Windows 10 device. The sync finished without issue for me after I added code to handle the failure of that one song. All the others seemed fine.
