John Seabrook’s The Song Machine: Inside the Hit Factory explores the industrialization of pop music, detailing how tracks are produced through a "track-and-hook" assembly line system, popularized by Max Martin. The book outlines how melodic, data-driven "sticky" music is engineered to maximize listener engagement, shifting focus from artistic expression to manufactured, playlist-driven hits. Detailed insights into the music industry's evolution can be found in the book.
