I thought it was just the biggest selling rock record since 2008.
Edit: Yeah, Born this Waysold 1.108 million the first week, and even discounting the 440K amazon digital sales, that's still more than this.
I could have sworn I read somewhere that since that record used a loophole they will not count albums that are that severely discounted in the future. I may be wrong, but that could be how it beats it? Not sure.
