slsk-batchdl

A batch downloader for Soulseek built with Soulseek.NET. Accepts CSV files or Spotify and YouTube urls.

Download tracks from a csv file:

slsk-batchdl test.csv

Use --print tracks before downloading to check if everything has been parsed correctly. The names of the columns in the csv should be: Artist, Title, Album, Length, though alternative names are sometimes inferred as well. Only the title column is required, but any additional info improves search results.

Download spotify likes while skipping existing songs:

slsk-batchdl spotify-likes --skip-existing

To download private playlists or liked songs you will need to provide a client id and secret, which you can get here https://developer.spotify.com/dashboard/applications. Create an app and add http://localhost:48721/callback as a redirect url in its settings.

Download youtube playlist (with fallback to yt-dlp), including deleted videos:

slsk-batchdl --get-deleted --yt-dlp "https://www.youtube.com/playlist?list=PLI_eFW8NAFzYAXZ5DrU6E6mQ_XfhaLBUX"

Playlists are retrieved using the YoutubeExplode library which unfortunately doesn't always return all videos. You can use the official API by providing a 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:

slsk-batchdl "title=MC MENTAL @ HIS BEST,length=242" --pref-format "flac,wav"

See which songs by an artist are missing in your library:

slsk-batchdl "artist=MC MENTAL" --aggregate --print tracks-full --skip-existing --music-dir "path\to\music"

  --yt-dlp                       Use yt-dlp to download tracks that weren't found on
                                 Soulseek. yt-dlp must be available from the command line.

  --config <path>                Manually specify config file location

  --searches-per-time <num>      Max searches per time interval. Higher values may cause
                                 30-minute bans. (default: 34)
  --searches-time <sec>          Controls how often available searches are replenished.
                                 Lower values may cause 30-minute bans. (default: 220)
  --display <option>             Changes how searches and downloads are displayed:
                                 single (default): Show transfer state and percentage
                                 double: Transfer state and a large progress bar
                                 simple: No download bars or changing percentages
  --listen-port <port>           Port for incoming connections (default: 50000)

  --print <option>               Print tracks or search results instead of downloading:
                                 tracks: Print all tracks to be downloaded
                                 tracks-full: Print extended information about all tracks
                                 results: Print search results satisfying file conditions
                                 results-full: Print search results including full paths

Files not satisfying the conditions will not be downloaded. For example, --length-tol is set to 3 by default, meaning that files whose duration differs from the supplied duration by more than 3 seconds will not be downloaded (disable it by setting it to 99999).
Files satisfying pref- conditions will be preferred. For example, setting --pref-format "flac,wav" will make it download high quality files if they exist and only download low quality files if there's nothing else.

Configuration files: Create a file named slsk-batchdl.conf in the same directory as the executable and write your arguments there, e.g:

--username "fakename"
--password "fakepass"
--pref-format "flac"

Notes:

For Mac you can use publish.sh to build the app.
The CSV file must use " as string delimiter and be encoded with UTF8.
--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.
The server will ban you for 30 minutes if too many searches are performed within a short timespan. Adjust --searches-per-time and --searches-time in case it happens. By default it's configured to allow up to 34 searches every 220 seconds. These values were determined through experimentation as unfortunately I couldn't find any information regarding soulseek's rate limits, so they may be incorrect. You can also use --random-login to re-login with a random username and password automatically.
