Musicality is very intuitive --- I think humans are intuitively attracted to music. That is why, in my view, musicality in terms of language and persuasion has a strong pathos: it appeals to our basic intuition, and would even argue that to something physical, closely interwoven with our intuition (perhaps this has a name in psychiatry, I don't know).

Think of the cultures and religions were music is used to go into a trance/to attain a higher level of spirituality. Music calls to something very deep-rooted in our feelings/intuition, and if language uses this element, is naturally strengthens a given message's appeal to our emotions.
