After a rough quarter which suggested that the variable-track pricing record labels fought so hard for was hurting digital sales, Warner Music Group has announced that it will no longer be licensing its music to services that offer free streaming. Warner hasn't specifically spelled out if that will apply to current deals with services like Last.fm, Spotify, and Pandora, or just to future deals, but it could put a damper on them if artists like REM, Death Cab for Cutie, and T-Pain were no longer available on those services.
