"I think everybody who relates to music is kind of isolated. It’s lonely. Everyone who uses the creative side of their brain is that much removed from reality. They are looking for answers wherever they can find them."
I admit, I was personally offended by this. I study music and social science (anthropology) in uni, though I started my degree in philosophy, politics and economics. I will probably write my dissertation on music and sociological influences, and this is why I have found it impossible to remain quiet on this subject.
I'll let the music stuff slide for now, but "Everyone who uses the creative side of their brain is that much removed from reality." is pretentious nonsense. Science and innovation requires imagination and creativity. Even Business is based on the success of an idea, and an original idea comes from creativity. Logic comes in when one takes steps to turn that idea into actuality OR to disprove or analyse the original idea. Science AND story writing AND lyric writing all draw upon observations of the world around us; people choose to perceive the world through numbers/concrete "answers" or through subjectivity, but either way the process to get there is a creative one.
Now I'll address "relates to music"...well now, as the wise and wonderful J. K. Rowling said at her Harvard speech, imagination is a defining characteristic in humans because it leads to Empathy. We can imagine, and then feel for ourselves, how other humans must feel. Granted, relating to artwork or music is almost always going to be introspective, but what about when we share this music with other people? They get to know us a bit better. Once we have their approval that they appreciate something about which we are passionate, we feel that much closer to them. Music is a social outlet.
What about when musicians have a freestyle jam session; they all fall into the same rhythm, they all progress in the same keys, and although they don't know what is going to come next there are no mistakes, just bonding on a a level that is almost a spiritual kind of social. This happens, of course, because scientifically the brainwaves synchronize with the sound and the muscles are told to keep up. Endorphins are released when we hear music that is pleasing to us. Also, music composition is about taking many isolated sounds and putting them together to make auditory sense; Just as painting is about taking individual colours and putting them together to create complex images; Just as writing a story is creating individual characters and putting them together to create a plot; Just as taking one element and putting it together with another will create a chemical compound. Creativity leads to creation.
If you don't use the creative side of your brain, you may as well be a computer. Creativity is the mental characteristic that places humans away from other animals: we can imagine answers to things that are right in front of us, beyond just looking at their physical forms!
The last sentence "looking for answers" is vague, but while I agree that to look to art to solve one's personal real-life problems is not particularly healthy; art therapy and music therapy may be a significant part of mental health care in the future. Lastly, using art and music to communicate with people on a large social scale, such as for peace movements, leads to unique understanding on both sides of borders, and that is a very special, deep part of art & music.
I don't mean to overreact. I have no problem with the OP, just with the incredulity I found in her statement.
