2. Fetch a Spotify playlist
3. Load your Traktor collection and match
Pick your collection.nml. It's read locally in your browser — nothing is uploaded.
Optional: connect Traktor's Music\Traktor\Stems folder to identify
collection tracks with generated stem sidecars. Stem-backed matches are shown first.
NMLify reads filenames only.
Generated stem status is unchecked until a folder is connected.
4. Find missing tracks on disk (optional)
After step 3, any tracks not selected from your collection are listed above. Add one or more folders that hold your music and we'll fuzzy-match those tracks against your filenames. Files stay on your machine — the browser only reads filenames, not contents.
Add as many folders as you like (e.g. main library on D:, promos on an external drive). NMLify remembers them between sessions in this browser — you'll just be asked to re-confirm access on reload.
After adding a folder, click Scan
on that row to index its filenames. Nothing is matched against
your not-found tracks until at least one folder has been scanned.
The Root path field on each row is optional — only fill
it in if you plan to export a Traktor playlist, so Traktor can
locate the files on disk (browsers don't share the absolute path
for security reasons). Supported formats: MP3, M4A, FLAC, WAV,
AIFF, OGG, WMA, ALAC, OPUS, plus Traktor STEM files
(.stem.mp4, .mp4, or .m4a).
No music folders added yet.
5. Crate history
Every crate you download is also saved here so you can grab it again later — even after closing the tab. Handy when you accidentally delete the file, want to A/B two crates you built minutes apart, or come back the next day without re-signing in to Spotify.
Crates live in this browser only — they're never uploaded. We keep the most recent 50 and prune older ones automatically.
