worked for Blizzard for a while done quite a bit of graphic / animation/ 3d modeling work there. I enjoyed it quite a bit. I prefer creative software work over structural however my main drive is towards mathematics in general which has been the baseline of a lot of things I liked, which could explain a strong inclination to music.
I personally have met people from all kinds of spectrum, financial, construction work, doctors, teachers who have a gifted level of genius in music. I think inclination to music has a deeper connection to the self-image. Self awareness in general.
cant help but comment on it from a mathematics perspective - not enough Data to make that assumption grins
If the right - left brain hypotheses were to be true, it would come with more exceptions than rules. Neuroscience has not yet been able to link hemisphere based activity to how your neural network gets trained.
