Taylor Alison Swift (born December 13, 1989) is an American singer-songwriter. Raised in Wyomissing, Pennsylvania, she moved to Nashville, Tennessee, at the age of 14 to pursue a career in country music. She signed with the independent label Big Machine Records and became the youngest songwriter ever signed by the Sony/ATV Music publishing house. The release of Swift's eponymous debut album in 2006 marked the start of her career as a country music singer. Her third single, "Our Song", made her the youngest person to single-handedly write and perform a number-one song on the Hot Country Songs chart.

Swift's second album, Fearless, was released in 2008. Buoyed by the pop crossover success of the singles "Love Story" and "You Belong with Me", Fearless became the best-selling album of 2009 in the United States. The album won four Grammy Awards, with Swift becoming the youngest Album of the Year winner. Swift penned every track of her Speak Now (2010) album without any co-writers. It debuted at number-one in the United States and the single "Mean" won two Grammy Awards. Swift's fourth album Red (2012) yielded the successful singles "We Are Never Ever Getting Back Together" and "I Knew You Were Trouble". Her fifth album, the pop-focused 1989 (2014) earned a Guinness World Record after it became her third consecutive album to sell a million copies in its first week in the US. Its singles "Shake It Off", "Blank Space", and "Bad Blood" reached number one on the Billboard Hot 100. The album received three Grammy Awards, with Swift becoming the first woman and fifth person overall to win Album of the Year award twice.

Swift is known for narrative songs about her personal experiences. As a songwriter, she has been honored by the Nashville Songwriters Association and the Songwriters Hall of Fame. Swift's other achievements include ten Grammy Awards, five Guinness World Records, one Emmy Award, 23 Billboard Music Awards, 11 Country Music Association Awards, eight Academy of Country Music Awards, and one Brit Award.

She became the youngest woman ever to be included on Forbes' "100 Most Powerful Women" list in 2015, and was the highest-paid celebrity in 2016.

U2 are an Irish rock band from Dublin. Formed in 1976, the group consists of Bono (vocals and rhythm guitar), the Edge (lead guitar, keyboards, and vocals), Adam Clayton (bass guitar), and Larry Mullen, Jr. (drums and percussion).^[1] U2's early sound was rooted in post-punk but eventually grew to incorporate influences from many genres of popular music. Throughout the group's musical pursuits, they have maintained a sound built on melodic instrumentals. Their lyrics, often embellished with spiritual imagery, focus on personal themes and sociopolitical concerns.

The band formed at Mount Temple Comprehensive School in 1976 when the members were teenagers with limited musical proficiency. Within four years, they signed with Island Records and released their debut album Boy. By the mid-1980s, U2 had become a top international act. They were more successful as a touring act than they were at selling records until their 1987 album The Joshua Tree which, according to Rolling Stone, elevated the band's stature "from heroes to superstars".^[2] Reacting to musical stagnation and criticism of their earnest image and musical direction in the late 1980s, U2 reinvented themselves with their 1991 album, Achtung Baby, and the accompanying Zoo TV Tour; they integrated dance, industrial, and alternative rock influences into their sound, and embraced a more ironic and self-deprecating image. They embraced similar experimentation for the remainder of the 1990s with varying levels of success. U2 regained critical and commercial favour in the 2000s with the records All That You Can't Leave Behind (2000) and How to Dismantle an Atomic Bomb (2004), which established a more conventional, mainstream sound for the group. Their U2 360° Tour of 2009–2011 is the highest-attended and highest-grossing concert tour in history.

U2 have released 13 studio albums and are one of the world's best-selling music artists of all time, having sold more than 170 million records worldwide.^[3] They have won 22 Grammy Awards, more than any other band, and, in 2005, were inducted into the Rock and Roll Hall of Fame in their first year of eligibility. Rolling Stone ranked U2 at number 22 in its list of the "100 Greatest Artists of All Time".^[4] Throughout their career, as a band and as individuals, they have campaigned for human rights and philanthropic causes, including Amnesty International, the ONE/DATA campaigns, Product Red, War Child and the Edge's Music Rising.
