This is an interesting one!For me, I will not wind up closing my eyes, as I cannot see words in my mind.
Which is why it takes me a hell of a lot longer to learn by reading the lyrics than it does when I form images (pictograms) of the essence of the lyrics. I can learn a song fairly fast this way. I am guessing it has to do with left/right brain dominance, or the amount of synaptic crossings between the hemispheres.
Or, I am completely full of shit...who knows?
Wait...don't answer that question
