The opening theme actually sounds like a generic African theme to me without belonging to a specific strain, but that's just my take on it. It sounded like "Lion King" music, it sounded like Gospel, and it sounded like Afro-Caribbean all al once, kinda.
And just to toss myusual argument in there, the opening them is the only part of the I don't really like, other than the unexplained presence of Chomper, which I won't be making a big deal of until I see the first episode.
