Just a short time ago went to play my usual Jean Michelle Jarre "oxygene" album (which often gets played) I have in my library, as a HD version I got from Qobuz, a while ago (I also have the normal release on CD, that I ripped ages ago). It came up as "Album not found", how can I delete it from the system, along with another Qobuz title, which comes up the same. Thanks
