New York - The Bono-backed (RED) charity for AIDS in Africa plans to launch a subscription-based digital music service on Monday that will offer exclusive tracks from artists including U2, Coldplay, Jay-Z, Elton John and Death Cab for Cutie, among others. The $5 per month (RED)Wire service will each week deliver one exclusive song from a major artist; one track from a lesser-know artist; a multimedia element; and a feature on how proceeds from the service are helping in Africa.
