Student told me about their depression over so many courses, holding down a job and having too many roommates. I asked if they listen to any songs about depression. Why would I do that he asked. I said I like them, even when I am down they are useful. Do many people write songs about depression, he asked. I said I bet more than 50% of all the popular songs are about depression, seems like that to me. He said that is interesting and he is going to look into it and thanks for cheering him up with this information.
