Music Sound

A promo single (short for promotional single) is a single that is released to club or radio outlets for the purpose of promotion of a song. It is not meant to be resold, but they are often sought out by collectors anyway. A promo single is usually sent to a radio station for it to play the radio version (which is often a radio edit, but can also be the original album version, or even a radio remix) of an artist's latest single. The promo single for radio stations often contains only the radio version of the song, but may also contain alternate radio edits, alternate radio remixes, or even call out hooks. Clubs often also played promotional singles (which are often released in the 12" Format) of singles with their latest remixes.
