What are some
musical biases that you may have?

I may feel music in my zone is better based on subjective thinking. there is folk music I have listened to that is awesome. without listening I would not have known, experienced this. so, this is‍ probably is true of most any music. it's all , with good intentions on the part of the artist, a gift. with appreciation , it becomes a art. so it is indeed healthy to venture out and experience a little 'different,' music once in a while.

c) from classical art

the answer is counterpoint.

counterpoint definition: "the art or technique of playing a melody or melodies in conjunction with another, according to fixed rules."

counterpoint is present in a lot of baroque music- such as bach (notably his wtc prelude and fugues) and scarlatti, but can also be found in music by mozart, beethoven. it can even be found in music as modern as john williams!
