Replying to Photo Presentation Due Tomorrow. Song Ideas?

Ok NS, here's the deal. I take a Grade 11 Computer Arts Course and our most recent project was to take Black and White Portraits, write reflections, and make a creative way to present them to the class. I decided to not follow the crowd by making a slideshow, but to make a flash animation of going through an art gallery and looking at all my portraits. Just finished up the animation after a few hours of work but now I need to clean it up with a song to put on top. That's when you come in. Any song suggestions for this? I was thinking of a slowish acoustic song but didn't have anything in mind. Help would be appreciated and karma will be awarded for those with help.

Sparknotes: Need a slow acoustic song that would go well with a presentation of black and white portraits.
