My app interface just changed a few days ago, and the whole "albums" management system happend to change at the same time. A lot of people are browsing the songs they listen to by albums, and i honestly think that removing non-fully saved albums from this library was not the greatest idea since every one of them are now only available somewhere lost deep in the "Titles/tracks" library. Are you considering keeping that change ? Thanks a lot for reading :).
