What are the Best Wedding Songs?

So, since I just got married Erica and I have been talking about this because we are going to have a wedding/party thing for our family since we rushed this on them. 

We have settled on one of my favorite artists ... Neil Young. Then we had to narrow down the song and came up with this:

It's pretty much my favorite song of all time.  What is yours?

I know there are some popular ones that I hate though, like:

• Journey "Faithfully"
• Etta James "At Last"
• Edwin Cain "I'll Be" which is a song I love, but I cannot take it when I hear it at a wedding.

Here are some of the popular ones that people are using now:

• Calvin Harris "We Found Love"
• Michael Buble "Everything"
• Bruno Mars "Marry You"

These are all terrible and mine is amazing and perfect, but we want to know what you think.
