Can listening to loud music damage brain cells?

After having listened to Heavy Metal for over 20 years I can honestly say that there is no simple answer.

It can be a source of energy and relaxation. It can stimulate your mind, inspire you, and provoke ideas and the thought process.

It will not change who you already are or turn you into something better or worse. YOU make your own decisions based on experiences and how you choose to translate and learn from those experiences and how you choose to view the world. YOU choose what you do to your brain.
