Jan 2005 Magnatune provides "Internet music without the guilt." Based in Berkeley, California, Magnatune is a record label with a 21st Century business model, offering consumers a unique mix of free and paid music. One of the first for-profit companies to adopt Creative Commons' copyright licenses into its strategy, Magnatune has amassed both an impressive buzz and a large artist roster. We recently spoke with Magnatune founder and CEO John Buckman about the music company's progress and plans, and how going "some rights reserved" can boost the bottom line.
