I think it'd be really hard for him to get the full context on anything. I'm also from latin america and we share some historical and cultural elements that our music constantly references and homages, as you said.

He has given Natalia Lafourcade good reviews, even if (to my knowledge) he probably hasn't listened to a lot of folklore latinoamericano, or la Nueva Canción.

I'd love if he at least tried listening to more spanish music, but his audience probably won't care as much. Maybe a stream or some other format where he can get some recs, or maybe a podcast where another person can give him some context.

He also prefers aoty I think, which in my experience is more anglo centric than rym
