This page aggregates measured, corroborated evidence: donors' iPhones recorded apps contacting this domain, every claim below was reported by separate accepted donations and published under a human verdict (later rows for an approved app inherit its verdict). A contact is a measurement, not an accusation — it does not show what data was sent.

What our research panel found AI-drafted · human-reviewed
We ask several independent AI models the same question and publish their answers separately — cross-vendor agreement is evidence against fabrication, and disagreement is worth seeing. 3 of 3 models answered, overall confidence high. A human reviewed this domain's claims before anything here published.
Anthropic Claude — first-party
sb.music.apple.com is a subdomain of apple.com, the app vendor's own domain, so this is first-party infrastructure for Apple Music; the exact function of the 'sb' host is not something I can determine from what is given. The app's label already declares collection of app interactions, in-app search history, diagnostics and user/device IDs, which would cover a first-party contact of this kind, so nothing here indicates an undisclosed flow.
OpenAI — first-party
The domain is under apple.com and music.apple.com, so it most likely supports Apple Music as a first-party service. Apple Music declares broad collection categories including app interactions, search history, identifiers, diagnostics, and purchase history; the contact alone does not establish an undeclared flow.
Google Gemini — first-party
The domain sb.music.apple.com is an Apple-owned subdomain operated for Apple Music, making it a first-party endpoint. First-party communication for normal app functionality does not constitute third-party data sharing.
