One hit wonder

A one-hit wonder is any entity that achieves mainstream popularity and success exactly once, and becomes known among the general public solely for that momentary success. The term is most commonly used in regard to music performers with only one top-40 hit single that overshadows their other work but is not limited to that field, such as having only one successful album with a string of hits.

Music journalist Wayne Jancik, whose book, The Billboard Book of One-Hit Wonders, published in 1997 and covering the period from the start of the rock and roll era in 1955 to 1992, defines a one-hit wonder objectively as "an act that has won a position on [the] national, pop, Top 40 just once."

Jancik's The Billboard Book of One-Hit Wonders, because of the publisher's limitation on size, only includes the top twenty One-Hit Wonders, or roughly half of the one-hit wonders that made the Top 40 from 1955 through 1992, and (because it was officially licensed by Billboard magazine) used the Billboard Hot 100 as its reference chart. The author has published a website "'One-Hit Wonders,' The Book", which includes all the one-hit wonders' profiles that were excluded from the book.

This formal definition can include acts with greater success outside their lone pop hit and who are not typically considered one-hit wonders, while at the same time excluding acts who have multiple hits which have been overshadowed by one signature song, or those performers who never actually hit the top 40, but, had exactly one song achieve mainstream popularity in some other fashion (that is, a "turntable hit" or a song that was ineligible for the top-40 charts). One-hit wonders are usually exclusive to a specific market, either a country or a genre; a performer may be a one-hit wonder in one such arena but have multiple hits (or no hits) in another.

In 2002, the American cable network VH1 aired a countdown of the VH1's 100 Greatest One-hit Wonders, hosted by William Shatner.

It listed musicians with only one American hit, regardless of international success, which has been substantial and long-lived for musicians like A-ha and Nena (see below). Under Jancik's criteria, A-ha, Falco, Vanilla Ice and Gerardo would not qualify for the list, as all four had additional hits in the top 20 outside their signature hits; they are nonetheless commonly considered one-hit wonders because those other hits did not survive in recurrent rotation. Los del Río likewise had two Top 40 hits, though both were versions of "Macarena".
