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. the branch of philosophy that deals with beauty and how it is expressed and appreciated

the answer is false i think
