iTunes Store stop kidding me with those silly duplicates!
I don't know who's responsible for stuff like this. The "Clone Wars" soundtrack is just another example of this duplicate album shit I just can't take anymore.
So for the love of god, if you have more than one version of an album and they all cost the same (!) just offer the BEST version. That way your customers won't feel cheated when they find out they just bought less for the same money (and I don't need to waste to time clicking around finding out which version offers the most).
BTW: Look at the title of the album in question and notice the irony.
