Feel-match = 100 − the measured distance between the two songs across 8 normalized dimensions (so 99% means their movement is nearly the same — not a metadata, genre, or popularity match). Raw distance: 0%. Same-artist songs are excluded, so the twin is always a genuine cross-catalogue discovery. When several songs tie within a couple of points, we feature the one that also shares a mood tag — the distance shown is always the featured twin's real distance.
