Ne users feel trapped by the very same notion. It strikes them as bland and limited. With such broadness of what can define music, why not experiment and get wild? Why not test our boundaries and see what crazy emotions music can make us feel? Let's see what we can incorporate into music and still have it be music. In this way, Ne tests the boundaries of context. It's random for the sake of random, but ultimately there are connections if it is still music. So I maybe see what you are saying, but I don't think it is either/or.
I was driving in the car listening to "Charmer" by Kings of Leon with some friends, none of whom were Ne dominant. They all hated it because, well, there is a screaming person in it. The first time I heard that song, however, I thought it was thrilling. Something delightfully weird yet something that still WORKS as music, and quite well. I saw the forest for the trees. My friends saw the "tree" of a person screaming weirdly in the song and wrote off the forest. That's Ne vs. other perception functions to me.
Btw I'm not saying an Si type (for example) can't like this song, but they are probably going to take a lot longer to. I had an ISFJ roommate who was famously slow to like anything that was just catching on, and then become obsessed with it once it had become popular and accepted for a while.
