This is probably way out there but it might be possible you could be born with a certain amount of preference in music too.
Certain traits are handed down to you from both parents so why couldn't things like preferences in music or even memories be handed down the same way. I know I had definite preferences in music even when I was 4 years old.
And I'm sure I saw some kind of documentary or something that showed even babies can have a preference for certain music.
