In the music industry, a pre-release cover version is a type of cover version that arises when a cover artist releases a version of a song before the original artist does.
 This practise takes advantage of a 'release window'; it occurs when an upcoming song has lots of airplay but has not yet been released.
 Pre-release cover versions are common in the UK because of the unique situation there in that songs by big acts get weeks of airplay before being released, giving cover artists enough time for session musicians and computer experts to record a near-exact cover version of the song.
 For example, UK #1, "Talk Dirty" by Jason Derulo ft. 2 Chainz, made #71 the week before it made #1 in the form of a pre-release cover version by Select Hits.
 Usually the original artist's record label will notice the cover version and release the original early; when Can You Blow My covered Flo Rida's "Whistle", Rida's record label rush-released the song mid-week.
 Avicii's "Wake Me Up!
" was intended to be released on 8 September 2013 however on 15 July 2013 the Official Charts Company announced that it would be released that week after a group called 'Spark Productions' recorded a pre-release cover version and made #26 on the UK Singles Chart with it.
