Yep. I'm pretty sure the weird onboarding process for Apple Music -- tap bubbles that represent genres you like, or something like that -- was very close to Beats's original process. I'm not sure it still does that, since it was kind of weird and confusing. Beats Music had a real focus on human-curated playlists rather than solely algorithmic ones, something that Apple Music kept.
Yes, it did, and MOG (what Beats bought and turned into Beats Music) had something like that too. Almost none of the MOG aesthetic is left today, though.
