Some audio files break at seemingly random
So every now and then, there is an audio file that Astiga did synchronise correctly, but refuses to play. Sometimes after resyncs this fixes/changes itself. Currently, Itzy's Ting Ting Ting and Bruce Springsteen's This Hard Land give this error. They show up and can be added to the playlist, but it refuses to play and instead Astiga just stops at the song until selecting another one that does work.
I always rip audio per CD yes it are single files that break, and the files play well everywhere else, so I doubt the files itself are the issue.
