Music is what keeps me alive, and what keeps me going. Life without music doesn’t have any meaning. It makes me feel, everything. I live the joy of the sound. Music has a profound impact on memory, and most of the psychological problems can be solved simply by tuning into the tunes when you were happy.
Discovering new music can help you define certain phases of your life, simply by discovering new tunes. Your brain will capture the sounds, and attach them to your current well being. Every part of your life will be attached to certain sounds and playlists. So when you replay some of those songs, you’ll be revoking the emotions of that particular period of your life.
Your milage may vary, but it works rather consistently for me.
