24 tracks on Apple Music's BEATstrumentals were measured on 2026-07-08 — spectrum, loudness, dynamics, stereo image and timbre. This is the playlist's sound as numbers, and your track can be scored against it below.
Third-octave spectrum of the BEATstrumentals lineup: mean level per band (line) and one standard deviation (shaded), in dB. Measured, not illustrated.
Your track's hook is measured the same way and ranked against the tracks already on the playlist — plus 58 other editorial lineups, so you see where it fits best, not just here.
Your file is analyzed and deleted — we keep numbers, not audio.
Tonally, BEATstrumentals is gently dark-tilted, close to the balance of most commercial masters: the median spectral tilt across its 24 measured tracks is -1.76 dB per octave, and the spectral centroid sits at 397 Hz — 334 Hz below the median of all 59 playlists we measure. Dynamically it is dynamic — peaks ride well clear of the average level, at a median PLR of 15.2 dB (track range 12.5–20.6 dB). Loudness range is 3.8 LU — loudness breathes moderately from section to section. The stereo image is solidly mono-compatible (median correlation 0.89, mid/side ratio 12.3 dB). Musically, the lineup shows tonal centers are present but soft (key clarity 0.61), a lean toward minor keys, highly repetitive structures (repetitiveness 0.92). Event density points to busy arrangements: 3.99 onsets per second at the median. On the engine's perceptual scales the lineup reads Warmth 85/100 and Brightness 22/100.

Median integrated loudness of the measured previews: -15.2 LUFS. Treat this as a property of loudness-normalized 30-second previews, not a mastering target — see what LUFS is.
The engine analyzes public 30-second previews of the 24 tracks on the playlist lineup of 2026-07-08: a 30-band third-octave spectrum, loudness and dynamics metering, stereo correlation and timbre statistics. The previews are deleted after measurement — only the statistics are kept.
The median peak-to-loudness ratio is 15.2 dB, with individual tracks ranging from 12.5 to 20.6 dB. Higher PLR means more transient headroom; lower means denser limiting.
The lineup's median stereo correlation is 0.89. If your track is far wider or narrower than that, it will stand out from the playlist's sound — which the Radar score reflects.
No. Editors weigh story, momentum and taste — things no analysis can measure. What the profile tells you is whether your track sounds like it belongs, so you can spend your pitches where the fit is real.
