The ones I have on Big Pink all have licensing information on them. I recently bought the just released Buckingham-Nicks - S/T mini LP CD album from the same source on Big Pink and that is licensed. I think it's like Japan in that stuff can get licensed in the far east that it can't be in the west sometimes. Don't know how that works. I'm not a Fleetwood Mac fan but I have always wanted to hear the Buckingham-Nicks album from '73 and it is really nice, from masters as well by the sounds of it. Plus there's loads of xtras. Anyway, I think you an buy those Korean titles with confidence.
