An extended play (EP) is a vinyl record, CD, or music download which contains more music than a single, but is too short to qualify as an LP. Usually, a CD single has around 10–28 minutes of music, an EP has up to 36 minutes, and an album generally has 30–80 minutes. Mini-LPs generally contain 20–30 minutes of music.[1] In the United Kingdom, the Official Chart Company defines a cut off between EP and album classification at 25 minutes length or four tracks (plus alternative versions of featured songs). .
