{Feature} Library: add Album-View for offline play / sorting (Metadata) of downloads-list (Albums)

[slynobody]

Problem Description

You download an album by simply clicking on the 'download' button.
In Offline-Mode you dont have the same usability the other way around: simply play that album.

You must hopefully find one or even the first song ot that album in a 'download' list -- and have to hope the following songs are downloaded according the album-sortage.

dont get me wrong: Great app! does nearly replicate spotify usability. But Offline-Users may encounter the missing album-view rather contraintuitive.

Proposed Solution

The Library-View currently only shows all Downloads in a simple List.
Why not
(1) let users sort the Downloads
(2) one of the sortage-criteria would be 'albums'
(when one is pressed you are guided back to the first of song of the albums (f.e. as playlist, f.e. temporary build in cache)

Should be simple to integrate (metadata should already be there) while giving a huge usability-benefit (esp. for offline-users)

Alternative Solutions

build playlists yourself be manually putting all songs of an album on one playlist = boring task, better done by the client itself.

also see this 2 year old reddit-issue usablity of caches inside downloaded playlists (reddit, not fixed)

issue: advertised funcionality: 'Caching and offline playback' (main page) not working

• Context: app used offline (WiFi/Mobile data disabled) with downloaded playlists.
• Reproduce Issue: go offline, switch to 'library' / 'downloaded playlists', choose album

  black screen, no direct cache display (hanging while trying to fetch data online)

• Symptom: Music playback works, but navigating 'back' results in black screens continuing to load indefinitely.
• ui: Album covers seeningly missing in-app , though they appear correctly in the One UI 6.0 notification panel.
• workaround: inside 'library' / 'downloaded playlists' press album > black screen > navigate back (iterate): album show up randomly (sometimes 3-4x back, sometimes 5-8 times), data is there but not handled right in this context.

if you dont want to fix this, please at least give hints on compiling source (link on main page).
