Billie Eilish's nearest ten neighbors span seven different subcategories, with no single kind dominating — a flat distribution where the scores range from 0.93 down to 0.89 without a clear break. Similarity here measures how closely two entities' audiences resemble each other in composition; a score of 0.93 means the audiences look nearly identical in shape, regardless of what the entities actually do.

The top neighbor is Gabriel Iglesias (0.93), a comedian — not a fellow musician. RUSS (0.91) is the only other musician in the top 10, sitting third. The rest of the set is a cross-kind mix: lifestyle creator NikkieTutorials (0.91), tech personality Pokimane (0.91), comedian Liza Koshy (0.90), artist Kat Von D (0.90), actor Tom Holland (0.89), influencer Manny MUA (0.89), and beauty brands ColourPop Cosmetics (0.89) and Anastasia Beverly Hills (0.89). The two beauty brands are the only non-celebrity entities in the set.

The pattern here is a broadly cross-kind audience shape — one that overlaps with comedians, lifestyle creators, beauty brands, and a tech personality at nearly the same rate it overlaps with other musicians, suggesting the audience composition is not organized around music fandom specifically.
