A Background Music System in a commercial environment is a music playback system that plays continuous background music, normally via a distributed public address audio system. It may include an element of zoning so volume levels are suitable for each area or zone of an environment. The music selection for a commercial background music system may also be profiled for a particular brand, venue or building so music that plays is suitable and automatically updated for the venue. Repeats within such a system are minimised (which helps staff and visitors) and can be interspersed with live broadcasts, adverts and if required staff training/company announcements.
