An extended play (EP) is a musical recording that contains more tracks than a single but fewer than an album or LP record.[1] Contemporary EPs generally contain up to eight tracks and have a playing time of 15 to 30 minutes.[2] An EP is usually less cohesive than an album and more "non-committal".[3]
An extended play (EP) originally referred to a specific type of 45 rpm phonograph record other than 78 rpm standard play (SP) and 33 rpm long play (LP),[4] but as of 2024[update], also applies to mid-length CDs and downloads as well.[5] EPs are considered "less expensive and time-consuming" for an artist to produce than an album, and have long been popular with punk and indie bands.[1][6] In K-pop and J-pop, they are usually referred to as mini-albums.[1]
Mini-albums and EPs are shorter than full-length albums and usually contain four or five songs [...] They are less expensive and time-consuming in production than albums, and they help to popularize new groups who otherwise lack the number of songs required for a full-length album.
