Steve Jobs posted an excellent article today backing a DRM-less music file for the masses. That means you play the file when you want and where you want independent of music players. Even iPods. From Jobs’s callout to the big four record companies: “If [DRM] were removed, the music industry might experience an influx of new companies willing to invest in innovative new stores and players. This can only be seen as a positive by the music companies… Convincing them to license their music to Apple and others DRM-free will create a truly interoperable music marketplace. Apple will embrace this wholeheartedly.”
UPDATE: iTunes currently protects songs that are already DMR-less at emusic.com. Not to side with the big record lables, but perhaps Steve is up to something else. More here.
