Lucas-owned Lucasfilm never bothered to release the original soundtracks after the SE. I’d say it’s a step in the right direction given that they’re putting both versions out there for people to purchase.
Not anymore. There is no digital download of the SE soundtrack anymore on iTunes or Amazon. Only the original soundtracks are available in mp3 now. Was thinking about buying the ROTJ album when I noticed this.
EDIT: the Ultimate edition compilation has also been pulled, but that’s more likely a copyright thing as that was distributed by Sony.
