The story

DJ tools say two records match because they share a key and tempo, then the mix falls apart live. This one came straight out of my own sets.

Cuepoint reads an already-analysed rekordbox library (read-only), recommends the next track and the exact mix-in point, and plays the transition back so the DJ can hear the call instead of trusting it.

Each suggestion is scored across 7 weighted components, with thresholds measured from real audio rather than guessed. Published as open source on PyPI, where it has 1,700+ downloads.
