Progressive pop is pop music that attempts to break with the genre's standard formula, or an offshoot of the progressive rock genre that was commonly heard on AM radio in the 1970s and 1980s. It was originally termed for the early progressive rock of the 1960s. Some stylistic features of progressive pop include hooks and earworms, unorthodox or colorful instrumentation, changes in key and rhythm, experiments with larger forms, and unexpected, disruptive, or ironic treatments of past conventions.

Pop music is a genre of popular music that originated in its modern form during the mid-1950s in the United States and the United Kingdom. During the 1950s and 1960s, pop music encompassed rock and roll and the youth-oriented styles it influenced. Rock and pop music remained roughly synonymous until the late 1960s, after which pop became associated with music that was more commercial, ephemeral, and accessible.
The Oxford Dictionary of Music states that the term "pop" refers to music performed by such artists as the Rolling Stones (pictured here in a 2006 performance).
