In my opinion, Background Music can be background music, only in the condition that it is originally and intentionally composed to be played-back as background in the mentioned places in the article like Elevators, etc...
The particular property that a Background Music must have, is that the structure of its melody and themes may not necessarily observe the Aesthetics rules in Musical Form.
Themes and melodies in Background music can be repeated limitlessly, because the audience never pays attention to the structure of music; in other words the audience just hears (Not listens to) Background Music.
I think, a serious (artistic) music (eg. Classical music or even easy-listening music that observes the rules of Aesthetics in Musical Form) cannot and must not be used as Background Music.
It is to be regretted that there are many Restaurent / Elevator / ... managers who select artistic and serious styles of music to be used as Background Music. --22.214.171.124 21:03, 1 May 2007 (UTC)
Intent of design or composition does not guarantee resultant type, form or use. Music to replace general white noise must only be non intrusive enough to not break out of general ambiance. —Preceding unsigned comment added by 126.96.36.199 (talk) 16:32, 6 September 2007 (UTC)
Many retail outlets now have their own specially commissioned "radio station" which plays an appropriate genre of music interspersed with advertisements or promotional information. There is obviously some overlap between background music and retail radio, but Wikipedia currently seems to be lacking a single article which groups these together. Perhaps a new article could usefully be created? Martinevans123 (talk) 16:41, 6 May 2011 (UTC)
