Nigerian afrobeat musician Seun Kuti is the son of the famous Fela. Seun's song 'IMF' - an acronym for, as he explains it, "international motherfuckers" - reflects his belief that the International Monetary Fund is complicit in making the rich few even richer and leaving the poor masses even poorer. In this week's My Song, Kuti talks about how the track was fuelled by his anger towards the IMF. That is, the organization in Washington, D.C. My Song showcases the personal stories behind the songs of Africa's most compelling musicians. You'll hear these musicians in their own words. No presenter, no interviewer - nothing to get in the way. Just African voices on African music.
