Independent music (often referred to as indie music or indie) is music produced independently from commercial record labels or their subsidiaries, a process that may include an autonomous, do-it-yourself approach to recording and publishing. The term indie is sometimes used to describe a genre (such as indie rock and indie pop), and as a genre term, "indie" may include music that is not independently produced, and many independent music artists do not fall into a single, defined musical style or genre and create self-published music that can be categorized into diverse genres. The term ‘indie’ or ‘independent music’ can be traced back to as early as the 1920s after it was first used to reference independent film companies but was later used as a term to classify an independent band or record producer.[1][2]
