The FIRST Django set is great, and contains legit transfer work, and material not reissued to death. So, on that basis I picked up the 2nd volume when it came out, and discovered EVERY track was in the Mosaic set of a few months before. Not only that, but to me the sound was a clone, which to me equals ripoff since Mosaic was first, and I didn't see any credit to either EMI or Mosaic.
Well, at least they don't ripoff someone else's work, and try and screw it up a little so it sounds "different" to cover up the source of the ripoff (i.e. Definitive).
