Fixes#6038 - Appends featured artists in the extraartists field to the
artist tag, similar to the MusicBrainz plugin. Works well with ftintitle
for consistency as well.
## To Do
May need adjustment for common artist delimiters used - but appears to
match the MusicBrainz standard at the moment.
My usecase needs the `convert` to not write tags so I can write my own
APEv2 tags. This PR adds a write_metadata option to disable the
`convert` plugin writing metadata to the converted files.
Fixes#5366 .
Adds removal of disambiguation from label names, in addition this PR
moves the Discogs disambiguation function out of the
MetadataSourcePlugin, and puts it in the Discogs plugin, keeping the
parent class more generic.
A config option has been added to allow disabling Discogs disambiguation
removal. Tests and docs are written for the feature, and shows no side
effects in other plugins that rely on the MetadataSourcePlugin.
I have different expectations around this [FtInTitle test
case](fcc9341360/test/plugins/test_ftintitle.py (L147-L151)),
which represents a song on an album by a **guest artist featuring a
third artist**:
```
{
"artist": "Alice ft. Carol",
"album_artist": "Bob",
"feat_part": None,
},
```
If this were Alice's album, the plugin would process the track, moving
`Carol` to the `feat_part` and changing the `artist` to `Alice`. But
because it's Bob's album, nothing happens. I don't want `Alice ft.
Carol` as an artist on Bob's album any more than I want it on Alice's
though 😭
This may be a bit of a corner case but it does happen reasonably often
in the wild:
```
Album: Flying Lotus - ASH (OST) (2025)
Track 26: Kuedo feat. Miguel Atwood-Ferguson - WHAT'S WRONG PEACH？
```
More commonly, this case applies to __compilation albums which use
`Various Artists` as an albumartist__.
Processing doesn't occur on these tracks in the current implementation
because of how
[`find_feat_part()`](fcc9341360/beetsplug/ftintitle.py (L57-L82))
kicks off:
```
# Look for the album artist in the artist field. If it's not present, give up.
albumartist_split = artist.split(albumartist, 1)
if len(albumartist_split) <= 1:
return None
```
As best I can tell, the code is setup this way to enable parsing of more
complex cases , like a song by `Hall & Oates` on an Oates album, which
is pretty clever. But giving up in cases where albumartist isn't in the
artist field seems premature when a reasonable parsing method exists
that doesn't require it.
So this PR proposes modifications to code and tests that enables
FtInTitle to process items whose artist doesn't contain the albumartist.
It seems like what someone loading a `FtInTitle` plugin would want by
default, but if that's a contentious take then I'm happy to put it
behind a config flag.
Thanks for your consideration!
Introduce a `--pretend` option to the lastgenre plugin, allowing users
to preview genre changes without making any modifications to their
library. This feature enhances user control by showing potential changes
before they are applied.
