It’s not an antibiotic, but to the extent that it influences your mood and attitude, or helps you vent your anger, stress of sadness, sure it has healing power.
Only you know what music moves you. For me, when I’m feeling blue, I put “Celtic Woman” on the boom box and they always make me feel better. If I’m really ill, quiet piano music or something “new age” can relax me. But sometimes its John Denver, or Metallica, or Chopin or Tchaikovsky.
Whatever it is for you, hope you feel better!
