Just want to add a note, though not really on topic (it's the only thing going through my head regarding this thread right now). As I've thought about the whole issue of music, I've come to realise that there is no such thing as "neutral" when it comes to music. For instance, some people--and I was among this group until fairly recently--will argue that instrumental music is by nature "neutral". I can understand the premise of this point: we each respond to different types, sounds, tones, etc. in music differently. What one might see as "confusion," another might see as beauty (a position I can understand, having been a lover of thrash metal, which can be quite intricate in the hands of a good musician, but which appears to be chaos to the average person). Proceeding from this premise, and going by the criteria normally given for "bad music,"
it's easy to say come to the conclusion that thrash metal instrumentals are not bad, but are neutral at worst. I think if Orthodox Christian principles are used, however, it will be seen that certain forms of music and/or expression can never be thought to be neutral-- or at least, can never be thought to be acceptable (saying that something being "neutral" makes it is acceptable is not necessarily true, and is definately not true in this case, IMO).

PS. Of course, the link is only my view of Orthodox principles, I don't think them infallible, or even perhaps "good"! They're at least a start though
