odd things while browsing user libraries

This issue is meant to help draw the big picture about uploading and sharing in funkwhale"s libraries.

Let say I have two albums of an artist called "Brad Sucks". I uploaded them both to my "mp3" library, which I keep private. But there is one of the album I would like to share with people somewhere, so I upload it again to a second "pod" library. How things appear in library is a bit surprising.

Actual results

I observe the following:

• the artist is said to appear (correctly) in both libraries.
• the "mp3" library reports only 1 album[1]
• the "pod library" reports 22 tracks for the artist[2]
• the "current usage" section highlights 50.6 MB of "skipped files"[3]
• the purge button does apparently nothing[4]

Expected results

• I'm not required to upload twice the same album in the first place (stating it here again just to ponderate the expectations below)
• the "pod library" reports 10 tracks for the artist
• the "mp3" library reports 2 albums
• the notice about skipped files gives some explanation about what's going on, and is easily distinguishable from usage information
• the purge button should be offered in very very few cases (ideally never), but when it is it does something
