Tangential, but the quote saying that musicians don't think about counting is wrong. For example, Chuck Berry said "My biggest influence was my mathematics teacher. Music is so much mathematics that it’s pathetic."
Musicians do a lot of counting, just that they stop at four. On the subject of which, music would make a lot more sense if the normal count went 'oh and one and two and three and'.
