Radiohead turned the music industry model upside-down when they decided to release their album "In Rainbows" online, allowing fans to choose how much they would pay for it, making a statement on digital media rights and where the future of the music business is headed. And now, they're using their songs to bring attention to the global plight of human trafficking.

Their video for "All I Need," released through MTV's EXIT or End Exploitation and Trafficking, shows a split-screen day of two boys, one white in suburbia, one Asian in a sweatshop. One boy spends his day learning in school and coloring in pictures while the other brushes glue over and over onto the soles of shoes. It's a simple portrait with a powerful message: "Some things cost more than you realize." At the end of the video, the pairs of shoes are side by side, one worn and one made.
