If you were a song, what song would you be and why?

I have not imagined which song I would be actually. But If I can be, I would like to be a song for people who feel tired and exhausted in their life. As I mentioned, I like to listen a music which has a comfort lyric. The reason why I like to hear is that sometimes I feel get a console and feel same as the people. I think a song is a magic of cure. As I am getting older, I think a life is not easy. I think a song is a good way to control our life. So If I can be a song, I want to whisper some nice words to people and makes feel be happy like a bed bracket in the winter season. This topic is very new and I have not thought about it in my life. I wish you understand what I want to say : )
