Welcome to The Weekend Stream, a relaxing weekly review of notable digital-only catalogue titles. There may be no CD or vinyl, but there's plenty of great new/old music to usher you into the weekend. Today's might be our biggest and best round-up of the spring: classic rock remixes, classic soul legends, rising rap icons, all kinds of '80s pop, a classic Broadway album making its belated digital debut - plus two urgent social causes we really want you to know about. David Bowie, Golden Years
