Energy is one of the six core dimensions in SongScore's Sonic DNA fingerprint, measuring the perceived intensity and activity level of a track on a 0-to-1 scale. High-energy tracks feel fast, loud, and noisy. Low-energy tracks feel slow, quiet, and calm.
Energy is calculated from a combination of spectral activity (how much frequency content changes over time), loudness (overall perceived volume), dynamic variation (how loudness changes throughout the track), and rhythmic density (how many percussive events occur per unit of time). It is related to but distinct from Arousal — a slow, intense orchestral piece can have high Arousal with moderate Energy.
Energy is one of the most important dimensions for platform fit. Spotify's algorithm strongly weights energy for mood-based playlist targeting. TikTok rewards tracks with rapid energy changes — a quiet verse that explodes into a high-energy chorus. YouTube Music's algorithmic recommendations show preference for consistent energy profiles. Understanding your track's energy curve — not just its average energy — is critical for release strategy.
