Of course, there is a cultural impact too, probably the most important factor in our musical taste. I mean, would you hear Samba if you were born in Finland? Well, but that's where thinks get tricky. For instance, why had rock'n'roll made such an impact on me, even though my parents mostly listened to regional music?
How can it be that, after all these years basically listening solely to rock/pop musics, I would like samba? Of course, I mean the so called 'classical samba' - yeah, I still don't like the new ones. Until some days ago I had never heard of Baden Powell de Aquino. Such a master of the strings.
How can it be someone likes Iron Maiden and Chico Buarque, or Death and João Gilberto?
Oh life.
