The Gradual Removal of the Human from Recorded Music
Below is a tempo analysis of the top five Billboard hits from 1960 to 2025.
The black line marks 2001, a milestone in automated multitrack timing correction. At the end of each decade: the share of its hits held to one fixed tempo, and the median movement (the typical tempo standard deviation inside a hit). The 2020s run through 2025.
The Crisis of Perfect Music
Music presents an image of how we exist in time together and how we may coordinate across difference. Since 2001, recorded music has increasingly coded embodied musical expression as error in need of correction. The result is machine-perfect music that presents to us an image of time none of us exist in, resulting in us perceiving difference as error in need of correction rather than collaboration.
One line per song, 1960 to 2025. Line height: the song’s tempo range, slowest to fastest, in BPM (capped at 50). Orange: one unchanging tempo. Hover or tap a line to see the song.

Certificate of Embodied Production
An independent certification mark for sound recordings produced without grid correction, pitch correction, or generative AI used to create, supply, replace, or reconstruct musical or lyrical content. Each submission is reviewed individually by an analyst against the published standard.
2001 marks a technological milestone in automating timing correction across multitrack drum recordings, including coordinated editing, gap filling, and crossfades.

Every recording behind the charts above: year by year, all at once, side by side and in full.
The top five, year by year
Pick a year. Each bar is that recording's full tempo range, centered on its own average tempo. A single tick with no bar means the analysis returned one unchanging tempo.
All 66 years at once
Each dot is one of the 330 year-end top-five chart positions, placed by year and by how much the tempo moved within the recording. Orange dots registered no detected tempo movement. Tap or hover any dot to see the recording.
Vertical axis is tempo standard deviation in BPM on a square-root scale, so the recordings with very large movement stay on the chart without flattening the rest.
