Question: What year was the single that once held the title of best-selling digital song of all time release? 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:Holm was born in Falköping, Sweden, the son of station master Carl Holm and his wife Olga (née Södergren). He passed studentexamen in Skövde in 1937 and then served in the Swedish Volunteer Corps during the Winter War in Finland from 1939 to 1940. Holm was commissioned as an officer in the Swedish Army Service Troops in 1941 with the rank of fänrik in the Norrland Train Corps (Norrlands trängkår, T 3) in Sollefteå. Holm attended the Royal Swedish Army Staff College from 1949 to 1951 and the British Army Staff College in England in 1954. He was appointed captain in the General Staff Corps in 1955 and he served in the expert investigation regarding compulsory military service from 1956 to 1958. Holm served as captain in the Älvsborg Regiment (I 15) in 1958 and he was appointed major in the General Staff Corps in 1959. The same year he attended the Swedish National Defence College. Holm was a member of the 1960 Social Emergency Committee (Socialberedskapskommittéen) and he served as head of department in the Defence Staff from 1960. He was then promoted to lieutenant colonel in 1963 and served in the Life Regiment Grenadiers (I 3) before being appointed colonel in the Defence Staff in 1964. In 1965, Holm was appointed regimental commander of Norrbotten Regiment (I 19) in Boden and the year after he served as chief of staff of the Bergslagen Military Area (Milo B).
 Passage 3: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.
