A musical IQ test?

Let me disclose that I am NOT a racist.
I am very, very fascinated by this psychometric test designed by Harvard neuropsychologists.
Musicans say this test fails to account for a more “global” musical picture in that it only seeks to measure one’s potential to play western pieces of pleasurable auditory stimuli. As we know musical IQ is positively associated with g at 0.4 so does this mean different races get different musical strengths, or is this just racist babble?
