If I'm going with the Cure, it has to be Just Like Heaven, because it came out right around when I met my future wife at the Melody and it became one of our faves, as well as one of our three wedding songs. The other two were E=mc2 by BAD (first song we danced to that night at the Melody) and Unbearable by the Wonder Stuff, because we love the song and it just seemed like a good goof for a wedding song, with the lyric: "I didn't like you very much when I met you (repeated twice more) and now I like you even less."
