I took a little time to listen to a few quick songs by the artists in question before reading the interview. Although most I could differentiate between, I kinda wish there was a bit more genres represented for most seem to fall under some kind of electronic category. Even Goukisan's "guitar" is just the product of a music program. But then again, we are on Newgrounds so perhaps I should have expected that.
I like the topic, Defining Music. A short background on the artists before the big question helps put everything in perspective. The answers certainly interest me, whether it's the amount of people interview who view music as expression or InvisibleObserver trying to separate listeners and composers (I can see a similar tone in some of his other responses). But then it feels as if the interview has apexed as everything else just seemed to be questions about these artist's music. Which sucks since I don't really like them that much. So I didn't bother to read it.
If there was just one thing I could change, I would have edited to make is a least opinionated and most factual as possible. Like I said I don't really like the songs you talk about and some comments on them I completely disagree with. In fact in the final notes I personally agree the least with InvisibleObserver and while that doesn't mean his responses aren't intriguing it kinda feels like the interview is displaying a bit of bias at some points. If I could change two things, I would scrap every question after the definition of music but double the amount of artists interviewed.
