Has anyone used contemporary music during their wedding ceremony?

I'm planning a wedding for June 2010 and I'm trying to take care of my little details first. I've seen many different sites offering suggestions for contemporary music (ie things you'd hear on the radio) during the ceremony. I have many songs I would love to have during at least the prelude, and I don't even really want to walk down the aisle to any version of a piano song. I just want to know if anyone has used music instead of clical songs during their ceremony. Also, any suggestions or examples would be welcomed. I would love the wedding to represent my fiance and I while still remaining elegant. Is contemporary music during the ceremony tacky?
