Meaningful song inappropriate for wedding?

I'm getting married and am making a list of songs I wanted to be played for the DJ and I was wondering if the song " on Fire" by Kings of Leon is inappropriate to play at my wedding. This song means a lot to both me and my fianc�e because this was our first time in Vegas together and they played this constantly plus it was on my 21st birthday which we had a great time. I definitely want music that people can dance to especially since all my aunts, uncles and cousins love to dance. I love this song and it never gets old to me but is it improper at a wedding?
