Question: Who produced the song that will.i.am claims that helped Obama win his election? Passage 1:Denson was born in Aliquippa, Pennsylvania, in 1975. A few years after his birth, his parents moved from Aliquippa to Baldwin, Pennsylvania, a suburb of Pittsburgh. He attended Baldwin High School where he played for the legendary WPIAL Hall of Fame coach Don Yannessa. Denson became only the second player in Baldwin High School history to start on the varsity football team as a true freshman. While playing in the highly competitive WPIAL, Denson had to face the likes of future NFL Hall of Fame player Jason_Taylor_(American_football) and future Super Bowl Champion Mike_Logan_(American_football) who would eventually become his 1997 Draft classmates. In his junior year, the Fighting Highlanders beat North Hills High School to win their first playoff game in over three decades. During his senior year, Denson was selected as a USA Today High School All-American and chosen to play in the prestigious Big 33 Pennsylvania Football High School All Star Game playing alongside Jon Ritchie and Ron Powlus.
 Passage 2: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.
