Singles, albums and compilations can have different functions and purposes in music distribution. While singles aim to showcase a specific song, albums offer a more comprehensive experience and compilations allow listeners to explore different artists or genres. Prices vary according to size and content, with singles usually cheaper than albums. An album, is a more comprehensive compilation of an artist’s songs. It offers the opportunity to present a wider range of styles, genres and emotions. An album can contain between eight and fifteen (or more) songs and offers the listener a musical journey through the artist’s creative world. Usually, albums are conceived as cohesive works in which the songs have a specific order and may be thematically or sonically related.
