"Do you remember the first song you streamed? Probably no more than you remember your first breath. Streaming and its main vehicle and commodifier, the Swedish company Spotify, have become so pervasive within music culture that its origins and impact are as hard to pin down as air. Liz Pelly's impeccably reported, persuasive book colors that air with detail and clarity, diligently and insightfully chronicling the 21st-century conquest of music lovers' souls. Mood Machine exhaustively explores the many aspects of Spotify's impact, from its tricky 'pro rata' economics to the pseudoscientific therapeutics of 'chill'; Pelly picks up every piece of the streaming puzzle and places it in perfect context. This book will intrigue the lay person, inform the artist, and cause music fans to think deeply about the hidden costs of making all those playlists."
--Ann Powers, author of Tori Amos and Traveling

"Here is the clearest and most thorough job of reporting-and-critique I've encountered on how Spotify, through a juncture of corporate interests, data science, surveillance, vibes theory, and cliché, has engineered a zombie impostor of musical culture. Liz Pelly helps you see and hear how it happened. Her work is an act of decency against degeneration."
--Ben Ratliff, author of Every Song Ever

"Mood Machine is so much more than a book about music streaming. Liz Pelly has painted a portrait of modern capitalism through the lens of Spotify, a mega-app that manages to encompass all the ways that Big Tech is both homogenizing and alienating, dulling our senses while offering the illusion of abundance. Spotify, in Pelly's hands, is a fun house mirror-world where our musical tastes and desires are warped to fit the needs of accumulation rather than art."
--Sarah Jaffe, author of From the Ashes and Work Won't Love You Back

"Much has been said about the somewhat tense relationship between artists, listeners and streaming. But with Mood Machine, Liz Pelly has written the definitive breakdown of Spotify and its influence on the music industry. Anyone wanting to learn more about playlisting, and to understand why they like what they like, should buy this book."
--Marcus J. Moore, critically-acclaimed author of High and Rising (A Book About De La Soul)

"We know intuitively that our relationship with music is changing - often for the worse. But to read how and why this relationship has broken down is devastating and infuriating. Liz Pelly lands this story on a hopeful note that will galvanize those of us who dream of a different future for the music industry. I couldn't put it down."
--Zoë Schiffer, author of Extremely Hardcore

"Recorded music has been a commodity since wax cylinders, but few writers have captured the current dizzying state of its commodification like Liz Pelly. In Mood Machine, she brings an insider's knowledge of the ways that Spotify and algorithmic recommendations have flattened our experiences as listeners, consumers, and participants in the music ecosystem. This isn't only a book about a crooked business, it's an argument for re-centering humanity in our listening habits."
--John Lingan, author of A Song For Everyone: The Story of Creedence Clearwater Revival

"My musical career happened at the end of the previous century, when major labels simply co-opted independently-created fads to maintain industry dominance. Mood Machine gives the definitive account of what followed: Spotify, an unprecedented wealth extraction machine which flattened music into metadata and exchanged inspiration for mere engagement. Author Liz Pelly writes with a reporter's instinct, a historian's reverence, a surgeon's precision, and a punk rocker's heart. Read this book, then joyfully go forth and work against everything its subject stands for."
--Tom Maxwell, author of Hell and A Really Strange and Wonderful Time
