Hmm no matter how hard I try, I can't get storm. Closest I can get is brain needle. It's just too clear to me that there are three syllables, and I can't map storm to the second half.
I had trouble hearing it too, so I closed my eyes to remove the flashing light as input and, I shit you not, just straight up told myself "you will hear brain storm". It was interesting not only in that that worked, but that my perception of the word was so completely different that it sounded nothing like green needle.
And no matter how hard I try, I can't get "needle". There's an "s" sound in there, how does anyone get "needle" out of that? :P
