Your skull, as much as what’s in it, may affect your musical taste — you may dislike a song because your head is too big (or too small) — suggests this study:
“Music of the Body: An investigation of skull resonance and its influence on musical preference,” Jitwipar Suwangbutra, Rachelle Tobias and Michael S. Gordon [a portion of whose skull is pictured here, encased in fleshy material], paper presented at the 165th Acoustical Society of America Meeting, June 4, 2013, in Montreal, Canada. The authors, at William Paterson University, Wayne, New Jersey, explain:
“since the size, density, and even shape of a person’s skull is somewhat unique, that resonance will vary across individuals. Our current research was designed to explore whether this uniqueness in skull resonance might have a direct influence on the kinds of music a person prefers…. The influence of skull resonance on music preference was studied across a series of experiments. Listeners were presented with a set of original melodies and were asked to judge how much they enjoyed each selection…. this research suggests that the skull [shape and size] might influence the music that a person dislikes rather than the music a person likes.”
