That last link is still just an article about a study, where is the actual paper? It doesn't make any mention of music. They only tested 12 people, and they were all men? That's a very small and not diverse sample size. They mention melody in quotes to describe the tonal variance between male and female voices but that is not what melody means. It's hard to say exactly what the author meant when i can't find the actual published paper making me question if it was peer reviewed to begin with.

And to clear up any confusion, music and language have overlapping cognitive resources as music is suggested to be a precursor form of communication for our species.
