Trackhound

Paste a link, get tagged music. Trackhound downloads albums, singles, playlists and single tracks by link from Spotify, Apple Music, Deezer, YouTube, SoundCloud, Last.fm and sites such as Bandcamp. A name works too: "Daft Punk - Discovery".

Titles, artists, track numbers, the year and the cover are read from the page behind the link, with no accounts or API keys. When the service streams the audio openly (YouTube, SoundCloud, Bandcamp), the track is taken from there; otherwise the same track is looked for on YouTube Music, SoundCloud and among YouTube videos. yt-dlp downloads it, and mutagen writes the tags and the cover art.

This package is the engine and the command line. Windows users who want the program with its window and everything bundled should take the installer from Releases instead.

Installing

pip install trackhound          # the engine and the `trackhound` command
pip install "trackhound[gui]"   # adds the window, started with `trackhound-gui`

ffmpeg and a JavaScript runtime (Deno, or Node.js 22+) have to be on PATH. yt-dlp needs the runtime to get audio from YouTube, and ffmpeg is needed for mp3, opus and ReplayGain. trackhound --check says what it found.

Command line

trackhound https://open.spotify.com/album/2noRn2Aes5aoNVsU6iWThc
trackhound "Daft Punk - Discovery" -f mp3 -o ~/Music
trackhound --dry-run https://www.deezer.com/playlist/908622995
trackhound --help

As a library

from pathlib import Path
from trackhound.engine import Downloader, Options, resolve

release = resolve("https://www.deezer.com/album/302127")
print(release.album.name, [track.title for track in release.tracks])

downloader = Downloader(Options(output_dir=Path("Music"), audio_format="m4a"))
report = downloader.download_link("https://www.deezer.com/album/302127")
print(report.summary())

The names importable from trackhound.engine are the public interface and keep working across minor versions; the modules behind it may change. Messages come in the system's language, Russian or English; set_language("en") fixes it. The engine writes to the trackhound logger and sets up no handlers of its own. Where Spotify refuses its pages to the network, use_relay(address) reads them through a relay abroad; the one-file relay is in the repository.

Errors

A message is for a person and may be reworded in any release. A program should look at the code instead, which is the same in either language and across minor versions:

from trackhound.engine import SourceError

try:
    release = resolve(link)
except SourceError as error:
    print(error.code, error.details)  # http_error {'service': 'Deezer', 'code': 503, 'url': ...}

for failure in report.failures:  # the tracks that did not arrive
    print(failure.track.title, failure.code, failure.message)

DownloaderError has the same .code and .details. ERROR_CODES holds the list:
