Can music help Jack?

My dog Jack has been sick for nearly a week now. He's had to go to the animal hospital three different days to get fluids and finally today the vet decided that he probably has salmonella. Poor little doggie has had not appetite and has also been throwing up and has diarrhea. I've had soft instrumental music playing in the background for several days as well as a natural soy candle that is called "warm pears." Tonight he seems a little better but still must go back tomorrow to get fluids and antibiotics again. Tomorrow I will suggest to the vet that he play soft instrumental music for Jack.
