Ed Sheeran's top 10 nearest neighbors span actors, video game franchises, and fellow musicians in a narrow band — scores run from 0.88 down to 0.84 with no single dominant pull. Similarity here measures how closely two entities' audiences resemble each other in composition, not how related the entities are in subject matter.
The subcategory breakdown tells the real story. Five of the ten neighbors are Actors — Jared Padalecki (0.86), Matthew Gray Gubler (0.85), Jensen Ackles (0.85), Misha Collins (0.85), and Dylan Sprouse (0.85) — making that the dominant subcategory in the set. Three neighbors are Brands in the video game space: Fallout (0.88), Bethesda Game Studios (0.84), and Bethesda (0.84). Only two neighbors share Ed Sheeran's own subcategory of Musicians and Bands: Panic! At The Disco at 0.88 — the highest score in the set — and Brendon Urie at 0.86, who is closely associated with that same act. No other musicians appear in the top 10. The remaining neighbor is American Horror Story (0.83), a TV Show.
The flat shape reflects an audience that overlaps broadly across entertainment subcategories — genre-spanning TV actors, gaming franchises, and a narrow slice of alt-pop musicians — rather than concentrating around any single kind.
