The shape of what got released: length, tracks, sequels, covers.

• Forty Minutes, Give or Take

  Seventy years of album runtimes say the album is a forty-minute idea that has now survived three containers. Vinyl held it at 38; the CD swelled it to 51; streaming has spent twenty-five years exhaling it back to 40 — while the track count never moved from ten.

• Nobody Fears Track 13

  2.8 million album discs, counted — the superstition isn't there. Track 13 dips less than 9 or 11 do. What albums actually worship is the number ten, and evenness itself.

• The 582-Hour Song

  49,228 recordings run longer than an hour; 210 run longer than a day; one runs twenty-four days. A logarithmic tour of duration's far end, where song titles become math.

• The Band That Releases Every Night

  97% of Phish's discography is live albums. Springsteen has out-released the Grateful Dead's vault. A census of the bands whose real product is the concert itself.

• The Half-Life of a Song

  How long does a song wait for its first cover? Thirty years in the standards era, sixteen in the album-rock seventies, and about twelve months today — measured over 230,774 first covers.

• The Most Covered Song, Actually

  Count recordings and Harry Potter audiobooks win. Count artists and the answer is Silent Night, with Coltrane's Naima beating Yesterday — a lesson in asking the database the right question.

• The Sequel Industry

  The ledger holds 53,067 albums whose titles end in 2 — and only 39,825 ending in 1, because Volume 1 is usually christened retroactively. A census of numbered music, in which the mightiest franchise artist of all time turns out to be "Various Artists."

• The Shape of Recorded Music

  39.6 million recordings plotted by year — with the Great Depression's 51% crash, the 1943 union ban, the CD explosion, and the 2020 bedroom spike all visible from orbit.

• The Skit Economy

  Tracks titled Intro, Outro, Interlude, or Skit quadrupled their share of the album in the CD era and collapsed in length from 2:16 to 1:20 — the word "Intro" changed species around 1990. A short history of the album's packing material.

• The Stretch Factor

  Same song, studio versus stage, measured across 39.6 million recordings — who doubles their material live, who plays it faster, and why the biggest stretchers working today are trance DJs.

• The Three-Minute Song, Measured

  A century of recording lengths in one curve — the shellac wall, the 2:38 trough of Beatlemania, the CD plateau, and the streaming shrink that is quietly bringing the short song back.
