Sound engineers, producers, and musicians explain how the recording industry quietly rewired what music sounds like, and why so few listeners notice. The film traces the loudness war, the studio practice of compressing tracks to maximum volume until dynamic range disappears, and follows it through to the MP3, a format built to shrink files by discarding audio data most ears supposedly won't miss. Engineers describe mastering decisions made for radio and earbuds rather than for the music itself, while interviewees argue that streaming has trained a generation to expect convenience and loudness over depth and detail, hence the film's blunt label, a McDonald's generation of music consumers. Vinyl collectors get their say too, not as nostalgic hipsters but as listeners chasing the dynamic range digital formats erased. The film moves between studio sessions, engineer interviews, and side by side audio comparisons that let you actually hear compression happening. It ends less interested in condemning technology than in asking what got lost in the trade for convenience.
