Where the data comes from

PlaylistMap indexes publicly available Spotify playlist data — playlist names, follower counts, track counts, genres and last-update dates — through Spotify's public interfaces. Our crawler revisits tracked playlists continuously and the public directory recomputes its statistics every night. We do not collect private listener data, and we never display personal contact information publicly anywhere on this site.

What our labels mean

Tracked — the playlist is in our index and its public stats are refreshed on a rolling basis.
Verified contact — our system found a working, publicly posted contact route for the curator (for example in a playlist description) and re-checks it over time. Contacts are only visible to signed-in members who unlock them with credits. If an unlocked contact turns out to be stale, we refund the credits.
Active — the playlist's tracklist changed on Spotify within the last 12 months (each directory page states the exact window it uses).
Last updated — the most recent track change we observed on Spotify, not the date we last crawled the playlist. Directory pages show our own refresh time separately in the page footer.

How the integrity checker scores playlists

The free playlist checker (model v1.0) blends six public signals into a 0–100 score: engagement coherence (30%), curator activity (20%), artist diversity (15%), addition pattern (15%), description check (10%) and size sanity (10%). Score bands: 75+ looking healthy · 55–74 mostly healthy · 35–54 proceed with caution · below 35 high-risk signals.

Limitations, stated plainly: the checker reads public Spotify data only. It cannot see play counts, listener geography or follower history, so its output is a risk assessment, never an accusation. Legitimate playlists that were bulk-imported or rebuilt can score low; sophisticated manipulation can score high. When a playlist exposes too little data (under 20 readable tracks or under 1,000 followers) we lower our stated confidence rather than guess. Results are cached for 24 hours.

Curators: claim, update or remove your listing

PlaylistMap lists playlists using publicly available information. If you curate a listed playlist you can claim your profile (and get pitches that match your rules), correct outdated details, or have your contact route removed from the members-only database entirely. We process these requests within 30 days, usually much faster.
