Hmmm. Okay. I'm not sure what you're trying to say, though. Are you trying to say that you think this ability is unique but not interesting or that it is interesting but not unique (I would say it is nice to have but not unique)? Is there a reason you have a particular interest in this ability, one way or another, or are you making a comment on the phrasing of the sentence? I looked at the articles you linked to, but the meaning of your comment is still unclear to me. Perhaps I am missing something obvious.
I am trying to say that the ability to play music in one's head without the presence of a musician or radio, etc. is a superpower, a form of mundane magic.
Granted that it is an awesome ability, how can we explain referring to this super power as "no special ability"? By noting common biases! People might think less of their musical superpower if they compare it to greater superpowers, such as the ability to freeze time, or the ability to compose music. Once one asks "how good is this superpower?", one might forget it's a superpower if the answer is "not comparatively good".
Before language, people must have thought without words. I often have the impression that I have a thought fully-formed in my head, yet I wait to listen to it unfold in words before moving on to the next thought. Perhaps I could think much faster if I weren't addicted to words.
Has anyone developed techniques for thinking without words?
This would have a little in common with Buddhist practices of emptying your mind, but wouldn't be the same thing. For one thing, Buddhists also try to empty their minds of images. More importantly, they are trying not to think, while I'm trying to think - just not unpack everything into words.
