Marking albums as listened, and sorting/filtering albums

[throwaway]

It would be great if musical albums are treated the same way as movies/series. So you could mark which album/song you've already listened to, and you could sort and filter albums the same way you can movies or series. E.g. if you treat albums the same as a series season, you can exactly see which song is next. And you can filter your music library to only show albums you haven't listened to yet.
