I need ideas for songs for an end-of-season slideshow. Any suggestions?

I coach a winterguard (flags, dancing, competition) team, and tomorrow is our end-of-the-season banquet. I am putting together a slideshow of pictures we've taken throughout the season. The types of pictures include practices, performances, getting ready for performances, and just goofing around at competitions. I don't want anything sappy but I certainly don't want techno music. Any ideas as to what songs I can use?
