Nine of Macklemore's ten nearest neighbors by audience shape are actors — a striking cross-kind pattern for a musician. Similarity here measures how closely two entities' audiences resemble each other in composition; a score near 0.82 signals near-identical audience profiles regardless of what the entities actually do.
Emmy Rossum leads at 0.82, followed closely by Emma Watson at 0.81 and Ryan Gosling at 0.80. Chris Colfer sits at 0.80 as well, and Cobie Smulders, Alyson Hannigan, and Darren Criss extend the actor cluster down through the 0.77–0.78 range. Mark Ruffalo (0.77) and Sarah Hyland (0.77) continue the pattern. The one exception in the top 10 is CollegeHumor (0.79, Humor Memes and Satire) — the only non-actor neighbor, slotting in at position five. No fellow musician appears anywhere in the top 10.
The shape is broad: scores span from 0.82 down to 0.77 with no single dominant neighbor pulling far ahead of the rest, and the actor cluster holds consistent weight across all ten positions. Several of the actors — Colfer, Hannigan, Smulders, Criss, Hyland — are associated with ensemble television, which may explain the coherence of the cluster, though the data speaks only to audience shape, not cause.
The overall picture is of a musician whose audience overlaps most strongly with fans of a specific tier of screen talent, with virtually no structural pull toward other musicians in the top 10.
