Does your set
actually flow?

Paste your tracklist — key and BPM for each song — and see the smoothest order to play them in, plus exactly where the flow breaks.

Needs key + BPM per track already on hand (from Rekordbox, Serato, Mixed In Key, or your own notes). Try the example below first if you don't have a list handy.

Key must be a Camelot code, e.g. 8B or 5A. Example: Blinding Lights, 4A, 171. Up to 12 tracks. Example keys and tempos come from published DJ references — your own software's analysis may differ slightly.

How this works

Same key + tempo scoring as the Match Score tool, applied to every pair of neighboring tracks.

Σ

Pairwise scoring

Every consecutive pair in your set gets a match score. The set's overall score is the average of those transitions.

↻

Reordering

The suggested order checks every possible sequence of your tracks and returns the highest-scoring one. Keep your opener locked in place, or switch to best possible flow and let track one move too.

⚠

Weakest link

The lowest-scoring transition in each order is flagged — that's the transition most likely to need a manual blend, transition effect, or skip.
