What are good songs to play at our wedding ?

I am so lucky that I am getting married to the best girl I have have ever met, and even if the wedding is not until next year, I feel that I needt to start planning some of the aspects already.

The point is that I am currently looking for some music to convey my feelings (for the reception). I really want it to be something from the music that we both like like Cohen, Cash, Sinatra, Suzanne Vega.

I am aware it a bit different artist, but for me atleast a lot of those hit a special nerve I cant identify, althou it just struck me that it might be a strong focus on the singer instead of the music.

I am open to other suggestions thou, but I would prefer something along the sound of the aforementioned.
