Question: What year was the single that once held the title of best-selling digital song of all time release? Passage:Described by will.i.am as "party album[s]", The Black Eyed Peas released the electronic dance-influenced The E.N.D. and The Beginning in 2009 and 2010, following the 2008 election of Barack Obama as President of the United States. The band welcomed Obama's election; will.i.am had recorded and released "Yes We Can", a single that promoted Obama's election campaign during the Democratic Party primaries, and often claims the song had helped Obama get elected. The band's most commercially successful single during this period, "I Gotta Feeling", was inspired by the band's perception of being "in the center of a ginormous change in America". The track became the best-selling digital song of all time until it was surpassed by Pharrell Williams' "Happy" in 2014. By the end of 2010, The E.N.D. had sold over eleven million copies worldwide, while The Beginning had sold over two million copies worldwide. The band had intended to return to the studio to create their seventh studio album soon after the release of The Beginning, though frequent delays and Taboo's diagnosis with testicular cancer in 2014, along with his subsequent treatment and recovery, led to the project being put on hiatus.
