In music, a radio edit, a radio mix, or a "clean version," is a modification, typically truncated or censored, intended to make a song more suitable for airplay and radio. It may be censored for profanity, vulgarities, words or a subject matter; or adjusted for length, instrumentation, or form. Radio edits may also be used for commercials, videos, tv shows, movies, events, video games, and single release radio versions, which may be denoted as the 7″ version. However, not all "radio edit" tracks are played on the radio.
