The name of the song is "Dangerously in Love 2". It was sang, written and produced by Beyonce Knowles, a R&B singer/song writer. It is also on her new 2003 album titled "Dangerously in love". The song is written from a first person's person's point of view, which is the singer (Knowles). This is particularly effective because the song is about her life and who else will know it better than herself. Since it's her life, she knows more about it than anyone else. She serves as the storyteller/narrator, telling her love life story from her own point of view (which is arguably the best). This method is also very effective because Knowles refers to herself in the song as "I", "My", "Me" and this creates a more persuasive picture that she knows what she is talking about. .
The topic and the theme of the song are two different things. The topic is the subject matter of the song while the theme is the statement being made about the subject. The theme of the song is the proclamation of her love to the man (and lover) who has provided it for her and has been her pillar of strenght and hope of her existance as a person. Without his love, she would be nothing. He also knows he is the only source of her joy, and therefore should always keep loving her. He loves her back and as long as they keep caring about each other, his love will protect her and "make the confusion go all away from this cold and messed up world". The topic, however, is simply love, the continuity and the difference it can make in a lonely person's life. The mood is the atmosphere created by the song. The mood is that if there's a person out there that loves you, it can make the world a better place to live in. The tone is the attitude taken by the singer towards the audience. The tone of this song is the difference the companionship and affectoin of a person who loves you can make in your life.
There are a lot of figurative language in this song that create very powerful imageries.
