“Born This Way” becomes GaGa’s first #1 on the albums chart. “The Fame” peaked at #2, and its extended version “Fame Monster” peaked at #5.

Lady GaGa is the most recent million seller, right after Taylor Swift’s “Speak Now” did it with 1,047,000 copies in October 2010. Curiously, Swift’s and GaGa’s albums share a similar strategy which didn’t help Swift much: Both had their albums discounted on Amazon.com for bigger first week sales ($0.99 for Gaga, and $3.99 for Swift). 440,000 copies of “Born This Way” were sold via the $0.99 HUGE discount, while only 40,000 of Swift’s total were off her discount back in October.

With such front-loaded digital sales from Amazon due to the super huge discount, “Born This Way” breaks the record for biggest digital debut of any album, with over 600,000 copies out of the albums 1,1 million coming from digital retailers, with Amazon contributing with almost half a million.

Lady GaGa’s new set becomes the 2nd biggest female first week sales in the history of the chart, after only Pop superstar Britney Spears whose album “Oops!…I Did It Again” sold 1,319,000 copies during its release week in 2000.

“Poker Face” crosses the mark of 6 million digital downloads in the U.S.A. this week, becoming only the third song to ever achieve this feature since the explosion of the digital market in late 2006. “Poker Face” joins Black Eyed Peas’ “I Gotta Feeling” (soon to be 7 million) and Gaga’s other song, “Just Dance” on the list of songs to have sold more than 6 million copies.

“Born This Way” is Gaga’s 3rd Hot 100 chart-topper, her previous ones were “Poker Face” and “Just Dance” in 2009.

According to The Worldwide Top 40 Albums Chart provided by MediaTraffic.de, “The Fame Monster” is the best-selling album of 2010 worldwide moving 5,9 million copies during the year.

Lady GaGa is followed closely by Eminem’s “Recovery” with 5,8 million copies and Justin Bieber “My World” with 5,6 million. The top 5 gets completed with Lady Antebellum’s “Need You Now” with 3,6 million copies and album-selling machine Taylor Swift with 3,5 million copies in 2 months for “Speak Now”.

“The Fame Monster” moved the same amount of copies in 2009 and charted at #2 on the year-end chart behind Susan Boyle’s “I Dreamed A Dream” which sold 6 million.

“The Fame” and “The Fame Monster” have now a total of 12 million copies sold.

Lady GaGa made several of the Year-End lists of Billboard magazine (the official magazine for US music charts), including #1 on The Artist Of The Year list.

Billboard has a different way to count their year and that’s how the lists are made. The 2010 Year-ends list counts from December 1, 2009 through November 30, 2010.
