i hear the french words "ou mes amis ..." 
That's it!
Sadly enough most people whom I might possibly address with this question that would have any relation to Africa are now bearing French passports and talk and sing similar tunes but in broken French or barbaric Harlem American (can't even call it English). They have lost their native tongues but in fact have gained nothing in return having got wrapped up in their self sufficient pseudo sub-cultures too far away from their respective motherlands.
Never mind -- I'll be keeping bananas out of my ears and I may eventually spot the origin of that file though I repeat that's generally not the kind of music I'm after...
[UPD] D*mn, am I not a linguist by one of my degrees or what, after all?!

Well that looks like some obscure
Kiswahili dialect (Swahili is a pan-African esperanto) that reads literally as follows:
Kule yu wingu mzuru
Kumezaliwa
Kumezaliwa
Kuumba ye
which, in my humble linguistic opinion, roughly amounts to some rhythmic Eskimo-style chanting about what one sees around:
It's gonna be a cloudy evening
Oh it is
Well it is
Yes it isVery informative for a 4:10 min. long song, isn't it?
