Most DJ advice is handed down rather than measured. We build MixReady on a corpus of published DJ sets, so where a rule of thumb can be checked, we check it — and publish what we find, free and without an account.

Every study here draws on the same corpus: more than 70,000 published DJ sets and growing, spanning four decades and 200+ genre labels, with over a million track-to-track transitions and growing. We do not publish the underlying sets, and every figure describes aggregate behaviour rather than any individual DJ's.
What BPM range can you mix between? ±3 BPM is only half the story. The rule that holds is proportional — about 6% of the tempo, roughly a pitch fader's travel. What genres mix well together? About 70% of real transitions cross a genre line. The map of which genres sit next to which. Does mixing in key actually matter? 22% of transitions are Camelot-compatible against 17% by chance. Real, but weaker than taught. BPM by genre, measured The tempo of 27 genres as actually played, with the ranges — not the round numbers every chart repeats. Do DJ sets speed up as they go? Median 126 BPM at the start, the middle and the end. Energy rises; tempo does not. Has dance music got faster? 126 BPM in every decade since the 1990s. What changed is the spread — from 20 BPM wide to 9. How old is the music DJs play? 47% of played tracks were released that same year. Only 5% were a decade old or more. How many tracks are in a DJ set? Median 18, middle half 13 to 27. The spread is more informative than the average.
