My favourite song

So far, I think that my favorite song is Grenade by Bruno Mars. The song is about a man that will do everything for a girl like catching a grenade from her, jumping out to the train for her, throw his head on the blade for her, he will go through all of this pain but she won't do the same for he. I think that the message of the song is to appreciate what other people are trying to do for you like the author of the song will kill him for her but she won't do the same.
