SUMMARY
Albums with multiple discs, where each disc is its own sub-directory, e.g.

`album/disc 1 - lorem ipsum/1.01 title.mp3`
`album/disc 2 - dolor sit amet/2.01 title.mp3`
etc.

appear to be considered unrelated albums by Elisa and appear multiple times in album view, once for each disc in a sub-directory. The album artist tag seems to be ignored in this scenario. This becomes quite the problem the more discs an album has. No other music player on Linux exhibits this behavior; I compared this to Lollypop and GNOME Music, both consider it one album, despite each album being in its own sub-directory.


STEPS TO REPRODUCE
1. Put a multi-disc album in the library folder of Elisa
2. Have each disc in its own sub-directory
3. The album appears multiple times in Elisa's album view

OBSERVED RESULT
Each disc appears as separate album entry in album view

EXPECTED RESULT
One album entry with multiple discs, no matter the underlying directory structure

ADDITIONAL INFORMATION
Putting all files into a single directory makes Elisa group them into one album. However, sub-directory structures shouldn't matter if the tags
