Depends on what exactly it is that you are looking to talk about the type of music. I think just instrumental maybe along the lines of Enya (some of her music can be particularly haunting if your taking that approach), movie soundtracks can be good too for providing background, but maybe avoid using anything with lyrics unless you really have to
Video wise....well there appears to be a fair amount on youtube, if you know how to save the video from there
hope it's of some help and feel free to pm if there's anything else
