Critics have their purposes, and they're supposed to do what they do, but sometimes they get a little carried away with what they think someone should have done, rather than concerning themselves with what they did.
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.
