While they are nowhere near my favorite band and for sure not my favorite AC/DC album (I'm more a Bon Scott fan than a Brian Johnson fan) I am answering the question as it was asked...
The album has sold an estimated 49 million copies worldwide to date, making it the second highest selling album of all time, and the best selling hard rock or heavy metal album, as well as the best selling album ever released by a band. On 13 December 2007, the RIAA certified it 22× Multi Platinum, recognising sales of 22 million in the United States. (Wikipedia)
