Apple TV Music captions on live concert videos

No captions for the SONGS themselves!!

on AppleTV in Apple Music there are live concert videos (previously recorded ones). For example, Billie Elish concert video for Bellyache x Ocean Eyes and Missy Elliot’s whole concert series. The captions detail “crowd noise” random ad libs by the artist on stage such as “how yall doing tonight? Love to be here!” And then when the song begins it will say “love no limit begins” and then the song isn’t captioned at ALL. Not a single lyric. Only stuff entirely outside of the song like “crowd whooping.”

why? Why is the actual song not captioned?? Why pay captioned to go to the trouble to caption these Live concerts then when the actual song begins they just put 🎶 for the entire song. These are the clips they put up post concert so it’s not really “live” it’s just called Apple Music Live
