Today I got yet another email from someone associated with a link-farm operation, telling me about an essay they'd published about the benefits of music in the schools - I should feel free to use my discretion about linking to this essay so that my readers could see it.
No way. I am not giving you the link, which would increase your PageRank and possibly push you up in search engine rankings. Anyway, the "reasons" you list could apply to just about any activity that individuals or groups commit themselves to.
Not to mention, your "essay" never mentioned music's intrinsic value.
