Some of the world's poorest countries in Africa and Latin America owe billions of dollars to the World Bank and IMF. For some nations, the debt is so large that paying it off seems impossible. Over the past few years, a movement has been growing calling for the large financial institutions to forgive debt to Third World countries. A new CD called Drop the Debt is one such effort. African and Latin American artists, many of whom are stars in their own countries, contributed songs about debt to the CD. NPR's Elizabeth Blair reports.
