Discussion about the philosophy of music, herp derp.
Some ideas to discuss:
Any judgement of music should be based solely on the elements of the music, and not on any extramusical factor, including a program, political climate, and especially audiences' reactions.
Likewise, definition of genre should be constrained to the elements of the music and the philosophy under which it was composed. Instrumentation should only be taken into account in narrow cases where a specific instrumentation is part of the genre (some EDM genres, for example, and you can't have a symphony for a single solo instrument or a concerto without a solo instrument). No broad "if it's orchestral, it's classical" or "if it's classical, it can only use acoustic instruments" definitions.
The purpose of art is always the expression of some extramusical idea or other, whether the artist knows what that idea is or not. (Often, there's no way for the artist to put into plain words the idea he's trying to express, which is why she must create art to express it.) Time and effort (as well as the idea itself) should not be considered when judging a work, as extramusical factors. (Indeed, a preoccupation with "putting in time and effort" could actually distract the artist from the idea he's trying to express.)
