We don't have good words for talking about this stuff (ironically), but I didn't intend to imply that the emotional aspect was less important than informational. Maybe "logical" would have been a better word for the latter. It's all information. Perhaps a better way to think of the split is that some of the audio content needs to be processed deliberately and sequentially—it has grammatical structure, words that need to be decoded, semantics, etc. It requires processing from the part of our brain that needs to deliberately pay attention to things. It's like reading or doing math. Meanwhile, some of it can be processed more intuitively. It's where we pick up tone and emotional intent. We will absorb that even if we don't deliberately focus on it—you can tell that someone is angry when they speak even if you don't know their language. Of course, understanding both of those requires integrating them together. The lexical content of their speech might tell you why they feel a certain way or what they feel that way about. But one way to look at music is that it's a sound artifact designed to deliberately convey "I'm almost all non-grammatical, it's OK to not focus on me." Again, of course, this is all pure conjecture.
