### Please make sure the question is worded well enough to be understood

## Description

Unfortunately, I cannot find the `artist` field in the JSON file downloaded from a SoundCloud song.

Recently, SoundCloud changed the way track artists are displayed, meaning that `uploader` no longer equals `artist`, and the `uploader` now has the freedom to define other track artists.

## Example

Consider the following sample song: https://soundcloud.com/i-am-aika/nefarious

When we view the site source: `view-source:https://soundcloud.com/i-am-aika/nefarious`, it has the field: `"artist":"I-YU, WarHawk, XYKI"`, but I cannot find it in the downloaded JSON:

[NA - NEFARIOUS.info.json](https://github.com/user-attachments/files/17535228/NA.-.NEFARIOUS.info.json)

If I run such a command:

```bash
yt-dlp --add-metadata --embed-thumbnail -o "%(uploader)s - %(title)s.%(ext)s" https://soundcloud.com/i-am-aika/nefarious
```

It downloads a file named `AIKA 🌸 - NEFARIOUS.opus` containing the following metadata:

- Artist: `AIKA 🌸`
- Title: `NEFARIOUS`

## Question

How can I download this song so that it will be named `I-YU, WarHawk, XYKI.opus` and contain this metadata:

- Artist: `I-YU, WarHawk, XYKI`
- Title: `NEFARIOUS`

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [ ] If using API, add `'verbose': True` to `YoutubeDL` params instead
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
