The new album released by Lady Gaga has become the biggest hit of 2011 so far. Although it outsold the rest of the Top 10 artist albums combined, Born This Way’s opening week was only the 36th biggest of the 21st century – and its arrival has blunted the impact of the four singles thus far lifted from it: Judas retreats from eight to nine (29,895 sales); Born This Way dropped from 16 to17 (22,495 sales); The Edge Of Glory fell from six to 18 (20,377 sales) and Hair slumped 13 to 68 (4,667 sales).

Nevertheless, overall sales of GaGa songs are heading rapidly towards the 6m mark, with the current total of 5,908,800 including 113,143 last week.

GaGa’s debut album, The Fame, opened at number three on sales of 25,228 copies in January 2009, and had its biggest sales week in the last week of the same year, when it sold 143,252 copies to occupy fourth position in the chart. It reached number one on its 12th week in the chart, eventually spending seven weeks at number one in four separate runs.
