Good songs to use in a video?

I am making a video for my Senior cl. We play this video at the end of the year at our farewell embly. So the whole high school comes in and watches our principle announce where we are going and what not. Then at the end we will play the senior video. We decided we didn't want any sad stuff. What are some good upbeat songs, not sappy, that work well in videos(like when I just have pictures going)? Also whats a song that I could use for the beginning that just sounds epic(something clical but really starts the mood right, of my senior cl being epic)? Thanks for the help.
