I have seen an advert for this and for 'Revenge of the Sith' produced by 'Elite Soundtracks'. This is the first I've heard of this company or these recordings. Does anyone know anything about them, please?
One of the ways to tell when such things aren't legit is to remember that any score of such significance would a) get huge publicity and lots of chatter here; and b) would be on a well known label of some kind. Anything else is going to be less than legitimate.
I usually use Soundtrack.net or Soundtrackcollector.com to see what has ever been released officially. Soundtrackcollector does list b******s, but they are listed separately from official releases and noted as such. I don't think Soundtrack.net ever has geltoobs listed.
