No one ever became, or can become truly eloquent without being a reader of the Bible, and an admirer of the purity and sublimity of its language.
So I think a writer should write what he loves, the people he relates to.
Music can help you through any kind of emotion. It can help you through a break-up, make you dance, or help you realize or understand something about yourself... and if I can sing a song and make someone feel those things then I will feel like I have made a difference.
