Song halp halp

I'm making another effort to crack an enduring musical mystery.

The enigma is a song, dated circa the early to mid 2000s. Vocalist was female, with a rather high-pitched, reedy voice, similar to Samantha Mumba's. Her singing tone was wistful. Chorus featured the phrase "mambo, mambo" and the song possessed a heavy tribal drumbeat. Overall air, while catchy, was not what I would call raucous or lively - certainly not like an actual mambo.

Anyone able to help me name it?

It would seem that this will forever rank among those great mysteries such as the Ripper murders, the Somerton Man, Jimmy Hoffa's resting place and who shot Kennedy. :(
