Alfred Matthew "Weird Al" Yankovic (pronunciation: /ˈjæŋkəvɪk/; born October 23, 1959) is an American singer-songwriter, music producer, accordionist, actor, comedian, writer, satirist, and parodist. Yankovic is known for his humorous songs that make light of popular culture and that often parody specific songs by contemporary musical acts. Since his first-aired comedy song in 1976, he has sold more than 12 million albums (as of 2007), recorded more than 150 parody and original songs, and has performed more than 1,000 live shows. His works have earned him three Grammy Awards among nine nominations, four gold records, and six platinum records in the United States. Yankovic's first top ten Billboard album (Straight Outta Lynwood) and single ("White & Nerdy") were both released in 2006, nearly three decades into his career.

Yankovic's success comes in part from his effective use of music video to further parody popular culture, the song's original artist, and the original music videos themselves, scene-for-scene in some cases. He directed later videos himself and went on to direct for other artists including Ben Folds, Hanson, Black Crowes, and The Presidents of the United States of America. In addition to recording his albums, Yankovic wrote and starred in the film, UHF, and television show, The Weird Al Show. He has also made guest appearances on many television shows, in addition to starring in Al TV specials on MTV.

Taylor Alison Swift (born December 13, 1989) is an American singer-songwriter and occasional actress. Raised in Wyomissing, Pennsylvania, Swift moved to Nashville, Tennessee at the age of fourteen to pursue a career in country music. She signed to the independent label Big Machine Records and became the youngest songwriter ever hired by the Sony/ATV Music publishing house. The release of Swift's self-titled debut album in 2006 established her as a country music star. "Our Song", her third single, made her the youngest sole writer and singer of a number one song on the country chart. She received a Best New Artist nomination at the 50th Grammy Awards.

Swift's second album, Fearless, was released in late 2008. Buoyed by the chart success of the singles "Love Story" and "You Belong with Me", Fearless attracted a crossover audience and became the top-selling album of 2009. The record won four Grammy Awards, with Swift becoming the youngest ever Album of the Year winner. Fearless also received Album of the Year plaudits at the American Music Awards, Academy of Country Music Awards and Country Music Association Awards, making it the most awarded album in country music history. In 2010, Swift released her third album, Speak Now, which sold over one million copies in its first week. She then embarked on the 111-date Speak Now World Tour, which was attended by over 1.6 million fans and has become one of the highest-grossing concert tours of all time. The album's third single, "Mean", won two Grammy Awards for Best Country Song and Best Country Solo Performance. Swift is currently recording her fourth studio album, due for release in the fall of 2012.
