It is sometimes considered interchangeable with power pop and skate punk. The genre has evolved throughout its history, absorbing elements from new wave, college rock, ska, rap, emo, boy band pop and even hardcore punk. It is distinguished from other punk-variant genres by drawing more heavily from 1960s bands such as the Beatles, the Kinks, and the Beach Boys.
It is defined by its fast-paced, energetic tempos, and emphasis on classic pop songcraft, as well as adolescent and anti- suburbia themes. Pop-punk (also punk-pop, alternatively spelled without the hyphen) is a rock music fusion genre that combines elements of punk rock with power pop or pop.
