I'm seeking the title of a song I've heard many a time, but don't know the name for. This one does not date from any earlier than 2003. It's got a heavy drum beat (something like tribal drums), and female vocals. These vocals are very... for want of a better word, reedy. With a lilt to them. Think Samantha Mumba. Lyrics escape me, but a very prominent phrase in the chorus is "mambo, mambo". The song has a catchy tempo, but its mood isn't a happy, upbeat one. The vocals have a wistful or reflective tone to them. Anybody recognize it?
