LADY Gaga has sold more than 1.1 million copies of her new album Born This Way in the US in one week.

And in doing so the dance pop provocateur set a digital sales record - with an assist from Amazon.com.

Billboard announced that Born This Way debuted at No. 1 on its Billboard 200 album chart, becoming just the 17th album to sell a million copies in its first week since SoundScan started tracking US sales in 1991 and the top-selling digital debut.

She is just the fifth female with an album that sold more than a million copies in the SoundScan era.
Lady Gaga's first No. 1 album sold the most copies of any debut in the US since March 2005 when 50 Cent's The Massacre sold 1.14 million. The last million-selling album was Taylor Swift's Speak Now in November.

Amazon's attention-grabbing download price of US$0.99 (92 cents) on last Tuesday and Thursday helped drive Born This Way to an unprecedented 662,000 in digital sales, pushing the album to nearly three times initial estimates by Universal Music Group. Amazon sold more than 440,000 of those copies alone, but with mixed results.

The online retailer did grab the spotlight it had hoped in its battle for a larger piece of the online market, which is dominated by Apple's iTunes. But it came with an image hit when customers overwhelmed Amazon's system.

Amazon's move has been deemed controversial by some observers who say the steep loss of several dollars an album was not worth the investment. Physical outlets also were upset at the advantage given to an online retailer.
