Grouping songs without albums in "unknown album"

[greku]

Thank you for the great application.

As a suggestion to improve the UI.
When browsing the database, selecting Artists in the drop down. The list of Artists shows up.
When clicking one of the artists, it shows the albums of that artists. Songs without albums do not appear.
I think it would be better if it would show those songs in an "unknown album".
It is not very logical to list Artists, click on one of them and not seeing the songs.

I have seen there is also a link to show the songs of the artist with the music note icon.

Instead of creating an unknown album, there may be other options like the default link could go to the list of songs.
In summary, it is not very logical to list Artists, click on one of them and not seeing the songs, or missing some of them.

Grouping songs without an album in a virtual unknown album is a nice idea. I will look into this option if it is feasable.

A setting to switch the behavior between show songs/albums will also be good idea.

myMPD v23.0.0 will provide both options.

As I'm now testing a bit with v23.0.0 branch. I have enabled the album_unknown config on my setup.
I see it is not creating only one unknown album per artist. Sometimes I get multiple of them.
Maybe this is due to the Date tag in the file? (at least in the following case, the Date tag is set for one of the song and that one ends up in a separate "Unknown Album", files are in same directory here)

In some cases, it is not a bad thing because two songs have different album covers. (the tags are as originally purchased from Bandcamp, they are located in separate folders in this case)

I'm also wondering how the unknown albums are sorted ? The sort is set to Albumartist in above views. In second case there is only one song per "unknown album", it seems to be sorting based on the song title instead of the album title. Could it be ?

[jcorporation]

Albums are grouped by the MusicBrainz AlbumID tag and as fallback by hash of AlbumArtist (Fallback to Artist) + Album + Date (Configurable). This is described here: https://jcorporation.github.io/myMPD/060-references/tags/#albums

Albums are sorted by a key that is generated from the sort tag value + :: + URI of first song in the album. There is no secondary sort tag. I think a user expects that the secondary sort tag is implicitly set to album name.

With the latest version, the album sorting is more coherent and Unknown album is located in alphabetical order.
So it looks good.
Thank you again for all the work you do on this project.
