Jay-Z and Kanye West are on their way to conquering the charts. The rap kings’ monumental album Watch the Throne is shaping up to have a blockbuster week.


The album only hit iTunes today, but early estimates are already in. In less than 24 hours, Throne has hit No. 1 on iTunes in over 20 countries. The album, which avoided leaking in advance, is on track to sell at least 400,000 to 500,000 copies in its first week in the U.S., according to Billboard.

Based on these figures, that would give Jay and Kanye the second-largest sales week of the year, behind Lady Gaga’s Born This Way, which opened with 1.1 million units.

Watch the Throne is available exclusively at iTunes until Friday, when it expands to other digital retailers and physical stores. Best Buy will carry the deluxe version exclusively from August 12-22.

Official first-week sales will be released on Wednesday, August 17.
