Did we mention that Billy Bragg is speaking at EconMusic, our London conference examining the digital music business on September 23? Billy has previously taken on MySpace for its policy on artist royalties and Bebo for building a fortune off musicians’ work. At EconMusic, Billy joins Last.fm, Mog.com and others to discuss digital licensing and making a living in the online age.
