Indie is a particular sound that has little to do with past associations of independent music. Indie also encapsulates a musical philosophy. Many artists utilize alternative instrumentation, jangling guitars, and may borrow from disparate genres such as folk, dance rock, and hip hop.
The term 'indie' is best known as being an abbreviation for the word 'independent'. This term was once used to differentiate between bands that were on a major record label and those that weren't.
