Pop rock is a music genre which mixes a catchy pop style and light lyrics in its (typically) guitar-based rock songs. There are varying definitions of the term, ranging from a slower and mellower form of rock music to a subgenre of pop music. Scholars have noted that pop and rock are usually depicted as opposites; the detractors of pop often deride it as a slick, commercial product, less authentic than rock music.

Pop rock has been described as an "upbeat variety of rock music represented by artists such as Elton John, Paul McCartney, Rod Stewart, Chicago, and Peter Frampton." In contrast, music reviewer George Starostin defines it as a subgenre of pop music that uses catchy pop songs that are mostly guitar-based. Starostin argues that most of what is traditionally called 'power pop' falls into the pop rock subgenre. He claims that the lyrical content of pop rock is "normally secondary to the music."

Critic Philip Auslander argues that the distinction between pop and rock is more pronounced in the US than in the UK. He claims in the US, pop has roots in white crooners such as Perry Como, whereas rock is rooted in African-American-influenced forms such as rock and roll. Auslander points out that the concept of pop rock, which blends pop and rock is at odds with the typical conception of pop and rock as opposites. Auslander and several other scholars such as Simon Frith and Grossberg argue that pop music is often depicted as an inauthentic, cynical, "slickly commercial" and formulaic form of entertainment. In contrast, rock music is often heralded as an authentic, sincere, and anti-commercial form of music, which emphasizes songwriting by the singers and bands, instrumental virtuosity, and a "real connection with the audience".

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.

Ricardo Iorio (born June 25, 1962 in Ciudadela, Gran Buenos Aires) is an Argentine heavy metal musician who participated in various of the most important metal bands in the country.

He was one of the founders of V8 (1979 –1987) and later founded the successful band Hermética (1988–1994). He has been the singer and main composer of Almafuerte since 1995. His songs are realistic urban stories dealing with the life of lower classes, as well as Argentine 'metalheads'. Even though he played the bass with every band he integrated, he has recently chosen Beto Ceriotti to be the new bassist of Almafuerte, remaining as the singer and main composer of the band (mostly lyrics).

Extremely nationalist, Iorio continuously proclaims in his songs and in the media the pride in being Argentine and Argentine history, and mixes native music styles like tango, Indian and gaucho culture with the heavy metal base of Almafuerte. The young people who goes to Almafuerte's shows consider him to be like a patriotic guru.
