This series is written from published material and its byline claims method rather than credentials, so the sources are listed. They are given as books and categories of material rather than as page citations; where a claim in the text is contested, the text says so at the point of the claim.
On the Swedish studio and the writing method. The most substantial published account of Cheiron and of the writers who came out of it is The Song Machine: Inside the Hit Factory by John Seabrook, which is the standard work on the topline-and-track division of labour described in the chapter on the camp and on the Stockholm house culture. It is a journalist’s account built on interviews and should be read as such, several of its principal figures gave it extensive access, which is both why it is detailed and why its emphases are theirs.
On melodic construction. The technical vocabulary in the chapter on melodic mathematics (tessitura, pickup, syllabic density, matched stress, answer phrase) is standard musical terminology and is set out in any songwriting or arranging text. The specific application of it to this repertoire has been the subject of a growing body of analytical writing, and readers who want the harmonic detail should go there; this book has deliberately kept to what can be described without notation.
On the Orlando business. The fraud, the guilty plea in 2008, the twenty-five-year sentence and the death in custody in 2016 are matters of public record, reported extensively in the American press and set out in the court documents. The relationship between Trans Continental and the groups is described in the members’ own numerous interviews over three decades, in the reporting of the period, and in the pleadings in the litigation, which was settled on undisclosed terms. The separate allegations of sexual misconduct were reported in a 2007 magazine investigation and in a 2019 documentary in which several individuals spoke on the record; Pearlman denied them and was never charged with a sexual offence. This book states only that, and readers should go to those sources rather than to summaries of them.
On the recording contracts and the arithmetic. The mechanics in Movement Four (recoupment, the dealer-price basis, packaging and free-goods deductions, controlled-composition clauses, producer points paid from record one out of the artist’s share, the structure of a 360 deal) are standard industry practice and are set out in All You Need to Know About the Music Business by Donald Passman, which remains the clearest general explanation available. The specific percentages and sums in this book are illustrative shapes rather than audited figures from any particular contract, and the text says so at each point. The actual agreements are private and this book has not seen them.
On the statutory mechanical rate. The United States rate is set by law and its history is published; through the period of this book it ran between roughly seven and eight cents per song per copy. European and Japanese rates are set differently, as the chapter on the territory problem describes.
On chart positions, release dates and sales. Billboard and the Official Charts Company archives. Sales figures reported by labels are label claims and are treated as such throughout; where a figure is a claim rather than an audited number, the text says so.
On the file-sharing collapse. The launch in June 1999, the litigation, and the 2001 injunction are documented; the subsequent decline in American singles and album sales is in the industry’s own published shipment data. The causal weight to assign to file sharing as against the labels’ own deletion of the commercial single is genuinely contested among economists who have studied it, and this book presents both and adjudicates neither.
On the performers’ own accounts. Several of the people in this book have published memoirs or given extended interviews about the period, including about the pitching of a song that became a defining record, about the pressures of an image strategy, and about subsequent legal arrangements. Where this book reports what somebody said about their own life, it is attributed to them in the sentence. Readers who want those accounts should read them in the subjects’ own words rather than in this summary of them.
Where figures are disputed (the terms of the Orlando settlements, what individual members actually received, the size of any particular advance, the precise split percentages on any particular song) the text says so rather than choosing. Those disagreements are not gaps in the record. They are the record.
