Music

Music can be divided into genres and subgenres, although the dividing lines and relationships between music genres are often subtle, sometimes open to personal interpretation, and occasionally controversial. Music may be played or sung and heard live, part of a dramatic ... work (a music theater show or opera) or film or TV show, or it may be recorded and listened to on the radio or another music device (e.g., iPod, CD player, etc.). — en.wikipedia.org
