- Do you agree that from experience and observation, we can tell that certain genres or fields appear to become completed?
- Does this concept or another concept best explain what is happening?
I understand that I was using the word "song" colloquially for a piece of music. I was not attempting to initiate a debate on the dictionary definition of a song or its characteristics in relation to other types of music.
The vocabulary you use conveys information about your background, experience, perspective, and conceptual framework -- in short, your epistemic state. Someone who un-self-consciously uses the word "song" in the way that you have is unlikely to be familiar enough with music to have good intuitions about its ultimate philosophical nature. My suggestion to you, therefore, is that before attempting to philosophize about the size of musical space and the proportion of it that is occupied by the mass-cultural products that seem to constitute the entirety of your experience, you acquaint yourself further with the higher realms of human possibility in this domain, if not others as well.
I don't mean this as a slapdown -- I genuinely think your beliefs would change if you had more knowledge.
This all being said, the question of the ultimate information-theoretic limits of interestingness in the universe is (plausibly) an important one, and (this being Less Wrong) I recommend the Fun Theory Sequence as a starting point.
I understand your point. My experience is in the genre of rock music (which is songs) and not in classical music, so my explorations into the metaphysical nature of music is based on extensive experience with songs (and not in other pieces of music). However, I believe at the metaphysical level that this idea applies to, there is not a substantial difference in examining the nature of songs and other pieces of music. That may make the perspective I'm coming from clearer to you, or we may have to agree to disagree.
I have not read the Fun Theory Sequence article, but you're right that is connected to this topic. I appreciate the link. Thanks for your comments!
