An extended play (EP) is a musical recording that contains more tracks than a single but fewer than an album or LP record. Contemporary EPs generally contain up to eight tracks and have a playing time of 15 to 30 minutes. An "EP" is usually less cohesive than an album and more "non-committal".

In music, a single is a type of release of a song recording of fewer tracks than an album or LP record, typically one or two tracks. A single can be released for sale to the public in a variety of physical or digital formats. Singles may be standalone tracks or connected to an artist's album, and in the latter case would often have at least one single release before the album itself, called lead singles.
