A little too much recourse to "truth is beauty, beauty is truth"-type fluff for me, but this article is generally worth a read, particularly in light of some recent discussions round here:
http://www.spiked-online.com/index.php?/site/article/4973/the UK government-sponsored Music Manifesto pays lip service to the idea that ‘music is important in itself’ but only as a prelude to treating music as a means to an end. So, after praising its alleged educational and therapeutic benefits, the authors of the Music Manifesto assert that ‘we believe that music is important for the social and cultural values it represents and promotes, and for the communities it can help to build and to unite’. Apparently music is also good for business and economic wellbeing - as the Music Manifesto declares: ‘We also recognise music for the important contribution it makes to the economy.’ The manifesto has little interest in music as such; instead its energy is devoted towards promoting the political, social and economic merits of music.
