Which song should I use for a wedding slideshow?

The Maid of Honour and I are making a slideshow for my brother's wedding in a few months. I'm looking for some song suggestions because the slideshow isn't entirely about just the two of them. The bride and groom each have a section of just themselves, growing up etc. Then there's family/pets, then friends, then the two of them together. It's basically the story of the two of them growing up individually, meeting, and getting to where they are today.

That said, we're looking for a few songs to cover everything. They don't have to be cheesy and romantic, they can be fun. They can be upbeat too, not necessarily the typical slow songs.

Good song or not, we're not using "I Hope You Dance." It's just too common in this sort of thing. Genre-wise, preferably country or rock but anything goes.
