A batch downloader for Soulseek using Soulseek.NET. Accepts CSV files, Spotify & YouTube urls.
- Download tracks from a csv file:
```
Usage: slsk-batchdl.exe [OPTIONS]
Options:
-p --parent <path> Downloaded music will be placed here
-n --name <name> Folder / playlist name. If not specified, the name of the csv file / spotify / yt playlist is used.
--username <username> Soulseek username
--password <password> Soulseek password
slsk-batchdl --csv test.csv --artist-col "Artist Name(s)" --track-col "Track Name" --length-col "Duration (ms)" --time-unit ms
```
You can omit the column names provided they are named predictably (like in this example). Use `--print-tracks` before downloading to check if everything has been parsed correctly.
--spotify <url> Download a spotify playlist. "likes" to download all your liked music.
--spotify-id <id> Your spotify client id (use if the default fails or if playlist private)
--spotify-secret <sec> Your spotify client secret (use if the default fails or if playlist private)
- Download spotify likes while skipping existing songs, and create an m3u file:
```
slsk-batchdl --spotify likes --m3u --skip-existing
```
You might need to provide an id and secret when using spotify (e.g when downloading a private playlist), which you can get here https://developer.spotify.com/dashboard/applications. Create an app, then select it and add `http://localhost:48721/callback` as a redirect url in the settings.
- Download the first 10 songs of a youtube playlist:
```
slsk-batchdl -n 10 --youtube "https://www.youtube.com/playlist?list=PLI_eFW8NAFzYAXZ5DrU6E6mQ_XfhaLBUX"
```
To include unavailable videos, you will need to provide an api key with `--youtube-key`. Get it here https://console.cloud.google.com. Create a new project, click "Enable Api" and search for "youtube data", then follow the prompts.
- Search & download a specific song, preferring flac and wav files:
```
slsk-batchdl "title=MC MENTAL @ HIS BEST,duration=242" --pref-format "flac,wav"
```
### Options:

Download tracks from a csv file and create m3u:
```
slsk-batchdl.exe -p "C:\Users\fiso64\Music\Playlists" --csv "C:\Users\fiso64\Downloads\test.csv" --username "fakename" --password "fakepass" --artist-col "Artist Name(s)" --track-col "Track Name" --length-col "Duration (ms)" --time-unit "ms" --skip-existing --create-m3u --pref-format "flac"
```
Download spotify playlist with fallback to yt-dlp and create a m3u:
```
slsk-batchdl.exe --spotify <url> -p "C:\Users\fiso64\Music\Playlists" --m3u "C:\Users\fiso64\Documents\MusicBee\Playlists" --music-dir "C:\Users\fiso64\Music" --username "fakename" --password "fakepass" --skip-existing --pref-format "flac" --yt-dlp
```
You might need to provide an id and secret when using spotify, which you can get here https://developer.spotify.com/dashboard/applications. Create an app, then select it and add `http://localhost:48721/callback` as a redirect url in the settings.
Download youtube playlist:
```
--youtube "https://www.youtube.com/playlist?list=PLI_eFW8NAFzYAXZ5DrU6E6mQ_XfhaLBUX" -p "C:\Users\fiso64\Music\Playlists" --username "fakename" --password "fakepass"
```
To include unavailable videos, you will need to provide an api key with `--youtube-key`. Get it here https://console.cloud.google.com. Create a new project, click "Enable Api" and search for "youtube data", then follow the prompts.
Files satisfying `pref-` conditions will be preferred. Files not satisfying `nec-` conditions will not be downloaded. For example, `--nec-length-tol` is set to 3 by default, which means that files whose duration differs from the supplied duration by more than 3 seconds will not be downloaded. Increase it to download e.g a youtube playlist of music videos with intros/outros, or disable it entirely by setting it to 99999.
Supports .conf files: Create a file named `slsk-batchdl.conf` in the same directory as the exe and write your arguments there, e.g:

```
## Notes:
- YouTube playlist downloading is unreliable since there are no track name / artist tags
### Notes:
- The CSV file must be saved with `,` as field delimiter and `"` as string delimiter, encoded with UTF8
- 40% of the code was written by ChatGPT
- Sometimes it starts vomiting text in the terminal (I don't know why), use --slow-output if that's an issue.
- `--display single` and especially `double` can cause the printed lines to be duplicated or overwritten on some configurations. Use `simple` if that's an issue. In my testing on Windows, the terminal app seems to be affected by this (unlike the old command prompt).
