Every recording

One list, one rule: most analyses first, ties broken alphabetically by address so a rebuild never reshuffles the page.

Most analysed first

The first 300 of 7,600, ordered by analyses. Every recording here cleared 125 independent analyses; 9,025 recordings did, and the top 7,600 of them have pages. The rest are listed in full on the 24 key pages, and by tempo. Measured up to 23.06.2022 — AcousticBrainz stopped collecting in 2022, so nothing released after that date is here.

Where the analyses did not agree on a key

135 recordings — 1.8% of the catalogue — have no key with more than 50% of their analyses behind it, so they are in none of the 24 key lists. The key printed on each of their pages is still the one most analyses chose; it simply has a minority behind it.

Automatic key detection most often splits between a key and its relative — the same signature, a different tonic — so a recording here is usually one of a pair rather than a mystery.
