Music Download

music-download

Download personal playlists / search hits with musicdl, then prepare an import-ready folder (audio + same-name .lrc) for local players.

Language: match the user. Prefer Chinese when the user writes Chinese.

Hard rules

1. Personal / educational use only. Do not help mass redistribution or commercial piracy. Remind the user to respect copyright and platform ToS.
2. Never print, commit, or paste full Cookie values into chat, git, or logs. Store cookies only in a local file with mode 600 (e.g. qq-cookies.txt).
3. Default quality is “good enough to listen” (compact MP3 ~192 kbps after download), not lossless. Only keep FLAC / pass VIP cookies when the user explicitly asks for high quality / Hi-Res.
4. Prefer writing files under a clear library root, e.g. $MUSIC_LIBRARY or ~/Music/musicdl-library/ or a path the user chooses.
5. After work, always give the user the absolute path of the folder to import.

OneMusic import contract (verified)

OneMusic accepts:

Workflow for the user:

1. Open OneMusic (Mac/iOS).
2. Import Music → select the prepared folder.
3. Play a track → open lyrics panel to verify .lrc sync.

Setup (first run)

Skill scripts live in ${SKILL_DIR}/scripts (directory containing this SKILL.md plus scripts/).

SKILL_DIR="$(cd "$(dirname "$0")/.." 2>/dev/null; pwd)"  # when inside scripts/
# From agent: resolve path of this skill's SKILL.md parent as SKILL_DIR

bash "${SKILL_DIR}/scripts/setup.sh"
# creates ${SKILL_DIR}/.venv and installs musicdl + browser-cookie3

Requirements:

• Python 3.10+
• ffmpeg on PATH (for ogg→mp3 and compact re-encode)
• Network access to music platforms

Optional env:

export MUSIC_LIBRARY="$HOME/Music/musicdl-library"

Default quality policy

Cookie / login is optional, not required for basic downloads. Only use when:

• Many tracks fail without login, or
• User explicitly wants higher platform quality

Workflow A — QQ / NetEase playlist (primary)

User provides a share URL, e.g.

https://y.qq.com/n/ryqq_v2/playlist/4211293243

source "${SKILL_DIR}/.venv/bin/activate"
python "${SKILL_DIR}/scripts/download_playlist.py" "PLAYLIST_URL" \
  --out "${MUSIC_LIBRARY:-$HOME/Music/musicdl-library}/from-playlists"

Then compact for import (default path import-ready/):

python "${SKILL_DIR}/scripts/compress_for_import.py" \
  --src "${MUSIC_LIBRARY:-$HOME/Music/musicdl-library}/from-playlists" \
  --out "${MUSIC_LIBRARY:-$HOME/Music/musicdl-library}/import-ready" \
  --bitrate 192k

Tell the user to import the absolute --out path (or the subfolder named after the playlist).

Workflow B — keyword / popular songs batch

# songs.txt: one query per line, prefer "歌名 歌手"; # comments allowed
python "${SKILL_DIR}/scripts/download_songs.py" \
  --list "${SKILL_DIR}/references/songs.example.txt" \
  --out "${MUSIC_LIBRARY:-$HOME/Music/musicdl-library}/popular" \
  --limit 40

python "${SKILL_DIR}/scripts/compress_for_import.py" \
  --src "${MUSIC_LIBRARY:-$HOME/Music/musicdl-library}/popular" \
  --out "${MUSIC_LIBRARY:-$HOME/Music/musicdl-library}/import-ready/popular" \
  --bitrate 192k

Optional cookies (higher quality / harder playlists)

Only when needed:

# macOS Chrome logged into y.qq.com — may prompt Keychain access
python "${SKILL_DIR}/scripts/extract_cookies.py" --domain qq.com \
  --out "${MUSIC_LIBRARY:-$HOME/Music/musicdl-library}/qq-cookies.txt"

download_playlist.py auto-loads qq-cookies.txt next to the out dir or MUSIC_LIBRARY if present. Do not echo cookie contents.

Manual fallback: user pastes Cookie header from DevTools into that file themselves.

Interactive search (musicdl CLI)

source "${SKILL_DIR}/.venv/bin/activate"
musicdl -k "晴天 周杰伦" -m NeteaseMusicClient,QQMusicClient,MiguMusicClient

Post-download checklist

• Count audio vs .lrc (lyrics optional but preferred)
• Convert any .ogg (OneMusic cannot import ogg)
• Run compress unless user asked for lossless
• Report absolute import path + size
• Remind: Import Music → select folder
