Yes, there is some great music on this set. That is undeniable. No, I wouldn't even dream of buying it. Basically, to sum it up, anything set that places work by Bessie Smith and Louis Armstrong next to the "work" of Will Smith or Mariah Carrey is an abomination that must be scorned at all costs. By placing art beside garbage, the attempt is to elevate the garbage, but the result is that it defames the art. The existence of this set insults me. I could just see the vapid Sony Music suits pieceing together this monstrosity--- This set, in a word, disgusts me. By placing the sublime beside the profane, Sony has insulted serious music fans everywhere. At best, this could serve as a thesis about the Kamikaze-decline of popular music over the years. Revolting. Go build your own record collection, don't let some dim-wit corporate tool do it for you.
