ELI5: How does your brain decide what kind of music you like and don't like?
gpt
There are two big factors that have affected your current judgments toward music: your upbringing (influences from those around you such as parents, siblings, and friends) and your cultural exposure (the types of music in your culture). In your upbringing, you were exposed to music through your family and the culture that surrounded you. Through these experiences, you learned how to classify certain sounds as pleasurable, un-pleasurable, etc. You have learned and adapted to what music is acceptable for certain occasions in your daily life: What music is good for dancing, religious practice, background, working, driving, relaxing, or putting you to sleep. Interestingly, the acceptable forms of music for certain occasions may vary from culture to culture; because of this, it is important to be open-minded to musical forms that you are not accustomed to. You may not like a particular form of music but remember that no one form of music is better than another; it is all a matter of perspective.

No matter what your taste in music is, you are a good listener! You may not be aware of all the details as to why you like certain sounds/music but you are automatically listening very closely when you are searching for music that stimulates you. Because you are so good at listening to music and sounds, you don’t even have to think about whether or not you like a certain type of music/sound: You Just Know! Keep in mind that you can always learn to enjoy and appreciate other forms of music. In the same fashion that you came to appreciate the music you do, it takes time and a lot of listening to appreciate music.
