A former political prisoner turned digital music CEO has teamed with Amnesty International on a viral music campaign designed to raise awareness of the genocide in Darfur.

Yobie Benjamin, CEO of digital music and e-commerce firm GoodStorm, created a widget that streams music from the upcoming Instant Karma CD-a collection of songs from 50 artists worldwide created to raise awareness and funds for Amnesty International's Darfur campaign.

Supporters can embed the widget in their MySpace profiles or other Web sites, which then streams music from the CD and allows interested users to purchase any of the songs from iTunes. The proceeds of all sales go to the Darfur campaign. The widget also links to an online petition for the campaign.

The Instant Karma CD goes on sale June 12.
