I definitely agree that music can be soothing. It all depends on the type of music. When I just want to be at peace, I play instrumental music. When I want to be uplifted, I listen to symphonic chamber music. Baroque music helps me reflect.
I enjoy all types of music, but I won't listen to country music over a long period of time because the lyrics can really be upsetting. For example, there was a time that my husband would listen to country music during his long commute home from work. After a while, he would walk through the door, irritated, suspicious, and just plain angry about everything. I discovered that he was listening to country music on his way home and asked him to turn the channel to something more upbeat... some golden oldies or something. He changed the channel and things got better for him. Country music is forbidden in our house unless we are only listening to a song or two. I only mention the thing about the country music to say that music does have an effect on our demeanor.
