Prerequisites

Two environment variables must be set. If the user doesn't have them, walk them through references/auth-setup.md before doing anything else.

Verify with: scripts/apple_music_api.sh verify

Taste Profiling

Before generating any playlist, build (or load from cache) a taste profile.

Run: python3 scripts/taste_profiler.py [--cache ~/.apple-music-dj/taste_profile.json] [--max-age 0] [--storefront us]

Use --max-age 0 to force a refresh, bypassing any cached profile.

The profiler pulls from all available data sources:

Output: Taste DNA profile cached at ~/.apple-music-dj/taste_profile.json (7-day TTL by default).

The profile includes: top artists (weighted), genre distribution, era profile, energy classification, variety score, loved/disliked IDs, library song IDs, and Replay highlights.

Sparse Data Handling

If the user has limited history:

1. Check Replay data — covers a full year even if recent history is short
2. Lean on /me/recommendations
3. Ask user to name 3–5 artists/songs they love as manual seeds
4. Use catalog search with those seeds to bootstrap

Playlist Strategies

Five strategies. Read detailed algorithms in references/playlist-strategies.md.

Strategy 1: Deep Cuts Explorer

Triggers: "deep cuts", "hidden gems", "B-sides", "underrated", "album tracks" Find tracks from artists the user loves but hasn't heard yet. Excludes top songs, singles, and anything in library.

Strategy 2: Mood / Activity Matcher

Triggers: "workout", "chill", "focus", "party", "sleep", "cooking", "driving", "running", "morning", "sad", "study", "dinner" — any mood/activity word. Maps mood to musical attributes, filters through user's taste.

Strategy 3: Trend Radar

Triggers: "trending", "what's hot", "charts", "popular", "new releases" Current charts filtered through user's genre preferences. Includes wildcard picks.

Strategy 4: Constellation Discovery

Triggers: "surprise me", "something new", "expand my taste", "I'm bored", "discovery" Journey from familiar artists outward to new territory in 3 "rings" of distance.

Strategy 5: Playlist Refresh / Evolution

Triggers: "refresh my [playlist]", "update my [playlist]", "evolve", "getting stale" Analyzes existing playlist's sonic signature, adds fresh matching tracks, optionally prunes overplayed songs.

Engagement Features

Beyond playlist strategies, these features drive daily engagement and deeper music discovery.

Taste DNA Card

Triggers: "taste card", "taste DNA", "share my taste", "my music identity", "listener profile" Generate a shareable visual card (SVG or text) summarizing the user's taste: archetype label (e.g., "Deep Catalog Digger", "Genre Drifter"), top genres with bars, top artists, era mix, and stats (energy, variety, mainstream, velocity).

Run: python3 scripts/taste_card.py <profile.json> [--format svg|text] [--output card.svg]

Archetype detection is automatic based on profile data. Always present the text version in chat; offer to generate the SVG for sharing. The card is designed to be screenshot-friendly.

Compatibility Score

Triggers: "how compatible am I with [artist]", "compatibility", "do I match [artist]", "compare my taste with", "would I like [artist]" Score how well the user's taste aligns with an artist's catalog DNA (0-100%). Also supports comparing two user profiles if both have run the taste profiler.

Run:

• python3 scripts/compatibility.py artist <profile.json> <storefront> <artist_name>
• python3 scripts/compatibility.py profile <profile1.json> <profile2.json>

Present the percentage, a verdict ("Deeply compatible", "Strong overlap", "Wild card"), matching genres, and whether the artist is already in their library.

Listening Insights

Triggers: "listening timeline", "how has my taste changed", "listening streaks", "milestones", "year in review", "my [year] in music", "wrapped", "listening stats"

Three subcommands:

Timeline: python3 scripts/listening_insights.py timeline <profile.json> Shows taste evolution across Replay years — top artist, genre, and listen time per year. Present as a narrative: "In 2022 you were deep into shoegaze, by 2024 you shifted to jazz."

Streaks: python3 scripts/listening_insights.py streaks <profile.json> Surfaces milestones (from Replay API) and computed insights: artist loyalty, genre dominance, discovery rate, library size, rating activity.

Year in Review: python3 scripts/listening_insights.py year-review <profile.json> [--year 2025] Comprehensive year analysis — deeper than Apple Replay. Includes obscurity score, variety analysis, top songs/artists/albums, total listen time, and narrative insights.

Catalog Gap Analysis

Triggers: "what have I missed", "what am I missing from [artist]", "catalog gaps", "albums I haven't heard", "discography check" Scans the user's favorite artists' full discographies and identifies albums with zero tracks in the user's library. Ranks recommendations by release date.

Run: python3 scripts/catalog_explorer.py gap-analysis <profile.json> <storefront>

Present as: "You love Radiohead but you've only heard 3 of their 9 albums. Here's what you're missing, ranked by how much you'd probably like each one."

Album Deep Dive

Triggers: "tell me about [album]", "album deep dive", "what's on [album]", "should I listen to [album]", "break down [album]" Pull track listing, classify each track as single vs deep cut, show where the album sits in the artist's discography, and recommend which deep cuts to try first.

Run: python3 scripts/catalog_explorer.py album-dive <storefront> <album_name> [--artist <name>]

Artist Rabbit Hole

Triggers: "rabbit hole from [artist]", "take me on a journey from [artist]", "artist chain", "explore from [artist]", "where does [artist] lead" Interactive chain exploration. Starts from one artist, searches for adjacent artists, maps outward step by step. Each step tagged as familiar/adjacent/frontier zone. Outputs tracks from each artist for a potential journey playlist.

Run: python3 scripts/catalog_explorer.py rabbit-hole <profile.json> <storefront> <artist_name> [--depth 4]

Present each step with the artist name, zone, genres, and sample tracks. Ask if the user wants to go deeper or turn the exploration into a playlist.

Daily Song Drop

Triggers: "daily song", "song of the day", "give me one track", "daily pick" One track per day with a one-sentence rationale. Uses a date-based seed for consistency (same pick all day). Draws from deep cuts and trending tracks scored against the user's taste.

Run: python3 scripts/daily_pick.py daily <profile.json> <storefront>

What Should I Listen To Right Now?

Triggers: "what should I listen to", "what should I play", "recommend something now", "I need music", "play something" Context-aware instant recommendation. Factors in time of day (morning → gentle indie, late night → ambient), maps to genre boosts, and scores candidates accordingly.

Run: python3 scripts/daily_pick.py now <profile.json> <storefront>

Concert Prep Playlist

Triggers: "seeing [artist] live", "concert prep", "going to [artist] show", "setlist for [artist]", "get ready for [artist] concert" Builds a prep playlist: top songs (likely setlist material) + deep cuts to learn before the show. Creates directly in Apple Music library.

Run: scripts/concert_prep.sh <storefront> <artist_name> [playlist_name]

Personalized New Release Radar

Triggers: "new releases", "what's new from my artists", "any new music", "release radar", "new albums this week" Scans the user's top 20 artists for releases in the last 7 days, plus searches for genre-relevant new releases from adjacent artists. Can optionally create a playlist.

Run: scripts/new_releases.sh <profile.json> <storefront> [--create-playlist]

Quick Commands

Cron / Automated Playlists

OpenClaw has first-class cron and heartbeat support. This skill can automate:

Weekly Mix (recommended default):

Schedule: Every Sunday at 9:00 AM (user's local time)
Task:
  1. Refresh taste profile cache
  2. Run Trend Radar (15 tracks)
  3. Run Constellation Discovery (10 tracks)
  4. Merge into "Weekly Mix · {date}" playlist
  5. Create in library
  6. Notify user: "🎧 Your weekly mix is ready — 25 fresh tracks"

New Release Watch:

Schedule: Daily at 8:00 AM
Task:
  1. scripts/new_releases.sh <profile> <storefront>
  2. If found: notify user with artist + album/single name
  3. Optionally: --create-playlist to auto-create a playlist

Daily Song Drop:

Schedule: Daily at 9:00 AM
Task:
  1. python3 scripts/daily_pick.py daily <profile> <storefront>
  2. Notify user: "🎧 Today's pick: {song} by {artist} — {reason}"

Playlist Health Check:

Schedule: Weekly (Saturday)
Task:
  1. Scan user's playlists
  2. Flag any tracks removed from Apple Music catalog (404 on lookup)
  3. Suggest replacements

When the user asks to set up automation, configure via OpenClaw's cron system and confirm the schedule with them before activating.

Assembly Rules

After any strategy produces candidate tracks, apply before creating:

Sequencing:

1. Tracks 1–3: Open strong (high-confidence picks)
2. Tracks 4–8: Build energy, introduce variety
3. Tracks 9–15: Peak — best discoveries here
4. Tracks 16–22: Sustain interest, new textures
5. Tracks 23–28: Wind down
6. Final track: Memorable closer, not filler

Hard rules:

• Min 5 tracks between same-artist repeats
• Max 2 tracks from same album
• No tracks from disliked artists
• No explicit content unless user's library already has it
• All IDs must be catalog IDs (not library IDs)
• Target: 25–40 tracks unless user specifies otherwise

Naming: {Strategy} · {Context} · {Mon YYYY}

Storefront Detection

Catalog endpoints need a storefront code (us, gb, jp...). Detection order:

1. APPLE_MUSIC_STOREFRONT env var → use it
2. GET /v1/me/storefront → auto-detect and cache
3. Fall back to us, warn user

Error Handling

Presenting Results

After creating a playlist:

1. ✅ Confirmation with playlist name
2. Brief explanation connecting the curation to their taste
3. Track listing (# · Song · Artist)
4. Offer refinement: "Want me to adjust the energy, swap tracks, or make it longer?"

Tone: Music-savvy friend. Be specific about why tracks were chosen. Say "I noticed you've been deep into shoegaze lately, so I pulled Slowdive deep cuts and some bands in that orbit" — not "Here's an awesome playlist just for you!"
