Home › Playlist Fit Checker
Every editorial playlist has a sound you can measure. Upload your track and see exactly where its hook sits among the tracks already on 59 real lineups — ranked, with honest verdicts, before you spend a single pitch.
Your file is analyzed and deleted — we keep numbers, not audio.
Profiles are rebuilt from current lineups, so your track is compared against this week's sound. Browse the measured profiles of all 59 playlists first if you want to see what the engine sees.
The engine finds your track's hook — the loud passage that recurs as an exact sequence — and measures it: 30-band spectrum, loudness, dynamics, stereo image, timbre. Those numbers are compared against statistical profiles of 59 real editorial playlists, built from public previews of the tracks currently on them. You get a ranked list of where your sound belongs.
They are seat percentiles, not vibes. CORE means your track would sit inside the tightest 60% of the playlist's current lineup by measured similarity; FITS means inside 90%. FRINGE and OFF mean the lineup sounds measurably different from your track.
59 editorial lineups across Spotify, Apple Music and Deezer — the Fresh Finds family, New Music Friday, POLLEN, RapCaviar, Techno Bunker, Peaceful Piano, Kickass Metal and more. The full list, with each playlist's measured sound profile, is at /playlists.
No. Genre tags are labels; this is measurement. A dark, heavily limited techno track and a bright, dynamic one carry the same tag but fit very different rooms. The comparison runs on spectrum, dynamics and stereo numbers, so it hears the difference.
No, and distrust anyone who promises one. Editors weigh story and momentum, not just sound. What fit tells you is where a pitch is worth your time — and where it almost certainly is not.
It is analyzed and deleted. We keep the numbers, never the audio. The free tier gives you eight runs a day.
