So much to unpack from that article. I do agree that people's music tastes are formed by their early environment as well as how they're exposed to it from adolescence, both through family and peer groups. I also feel that these early experiences greatly influence how people's relationship to it develops, just like with visual and performing arts, literature, etc. Undoubtedly, a lot of people, simply love certain music because it connects them to life experiences.
Those that are taught music more in depth through instrument lessons, family tastes, or a friend's sheer enthusiasm for a song, often take the initiative to explore. Although some may disagree, I believe true listening is a learned experience. I'm not saying that people can't have a gut reaction to music and automatically like it (or not), but a little guidance on how to listen, especially to certain genres, really enhances the experience and nurtures a love for music. I've experienced this personally many times with genres like orchestral music, jazz, loads of rock genres, world music, and other styles.
