Every track has a fingerprint

Song DNA is built from the same studio-grade analysis the producer sees on stream. It doesn't store your audio, only these measurements.

• tempo4 pts

  How fast the song moves and how tight the timing feels.

• key4 pts

  The musical key and whether it leans major (brighter) or minor (darker).

• energy24 pts

  How the intensity rises and falls from the first second to the last.

• bands7 pts

  The tonal balance, from sub-bass up to the airy top end.

• loudness4 pts

  How loud it is overall, how punchy, and how much the level moves.

• stereo2 pts

  How wide the mix sounds and how well it holds up in mono.

• structure6 pts

  How the song is laid out: intro, how soon the hook lands, sections and repeats.

• mood2 pts

  A rough read on how happy or dark, and how calm or energetic, it feels.

• timbre5 pts

  The texture: bright or warm, bass weight, muddiness and harshness.

From those numbers we also pick a few plain-word traits, for example:

Each track's 64 numbers are drawn as a glowing double helix in Neon Rush green. The twist, thickness and brightness of each rung come straight from your track, so a driving, bass-heavy song looks different from a laid-back acoustic one.

The producer sees it in the track panel, and it can fill the screen during the live presentation.

After your review, you can download a square 1080×1080 Song DNA card from your private status link. It shows your helix, title, artist, key details and top traits. Tracks on the Showcase have a card too.

We compare your DNA with tracks in the public archive and show the closest ones, each with a similarity score from 0 to 1. Only tracks that are already public are ever matched: Showcase posts and featured tracks. Private submissions are never shown to anyone.

When you make an AI Music Video, your Song DNA picks a starting style: the theme, color palette, film look and character. Tempo and energy set the pacing: high-energy tracks cut every couple of bars, mellow ones hold each scene longer. You can change any choice before you order.

From the same DNA we pick your song's mood: one of seven, plus a runner-up. It's a simple, transparent rule, not a guess about your lyrics. Tempo, major or minor key, energy and how the dynamics move all add points to each mood, and the highest score wins. The explanation always says why, for example "Purposeful: steady 104 BPM, major key, moderate energy, building dynamics."

In an AI Music Video, the mood sets the lighting, the setting, the character's expression, the camera feel and how scenes cut. You'll see "Your video mood" before you order, and you can still change the look.
