Final answer:
The provided texts discuss Caribbean and African music influences, but do not specify where the term 'mambo' first appeared in a song title. Additional research is needed for an accurate response.
Step-by-step explanation:
The question refers to the history of the word mambo in a song title and its initial appearance, which would be connected to the Caribbean and its complex musical background.
The mambo is a genre that, like salsa, has its roots in the fusion of African and Spanish cultural influences in Cuba.
While the provided texts reference several aspects of Caribbean and African music, along with notable artists like Chéri Samba and Gonçalo Mabunda, they do not directly answer the question of where the term mambo first appeared in a song title.
For a factual answer regarding the origin of mambo, additional research outside of the provided materials would be required.
