Can you please elaborate on what features you think are the compelling ones?
What I see on that page is this:
Play over 100 million songs, always ad‑free. Hear next-level sound quality with Spatial Audio1 and lossless audio.2 Take centre stage with Apple Music Sing. Access exclusive interviews and live concerts. And listen across all your devices, online or off. The music app for music lovers is here.
Spatial Audio = "most people don't care" or simply don't even like it
Lossless Audio = Available on other platforms, but also something that a lot of the mainstream doesn't care about either, depending upon their listening context and devices, etc
Apple Music Sing, Interviews and Live Concerts -- It's all just super niche neat side stuff that isn't going to drive interest on its own for most people.
