I dislike the term "world music"; it's basically an inaccurate catch-all term used for Mediterranean, Asian, African, and often enough Latin American folk music in a culture where "folk music" is based on the folk music traditions of the British Isles and regions of France and Germany and maybe a few other "Northern Europe" regions. But already, I digress....
I also dislike most "pagan music". I've gotten very selective about my cheesy gothic pop-rock with my old age (no offence to Inkubus Sukubus fans in the room), and when your paternal grandfather and both maternal grandparents got off the boat from said Isles, your step-mother, who was not Anglo-Celtic in any ancestral manner, becomes obsessed with Irishness after marrying your father, and half your teachers feel compelled to tell you about how they felt when they say Michael Flatley in Riverdance, or that Michael Collins film, the Celtic folk-based filks that often uncritically dominate the pagan community get really boring, really fast. To make things worse, when interacting with "pagans" on an interfaith level, rather than other Hellenists exclusively, my opinion is not a popular one: My religion encourages competition and bettering oneself --it is completely fair to offer a constructive critique of another's "musical offering" among Hellenists. Many ancient Hellenic festivals featured contests where, yes, there would be a winner and sometimes even a clear loser. I once hosted a Mouseia poetry contest where a participant later harshly criticised me in their own blog cos they didn't win for a very good reason --they submitted a very generalised poem of Olympian reverence, and the contest guidelines were for a poem dedicating a community website to the Moisai. In what basically amounts to an experience-based community with a large interfaith focus, where the status quo is that all good faith efforts to produce something "good" necessarily produce only "good" works, the idea that some works are necessarily better than others will not make one many friends.
