This is a thread that could go on and on. Seems like marriage isn't about how many people are tying the knot, officially or no. It's about commitment and what your heart says about someone.
I'll be up front here - that's an expression from my generation and I don't mind dating myself. I feel very suspicious about commitment. It can be a nasty proposition. But I led a sad life - and many don't feel that way.
Seems like songs about commitment and or songs about the heart couldn't go far wrong. The radio spends all day every day spinning songs that will speak to you personally. Since there are a lot of us this takes a lot of time. Finding a song that talks to you and talks to the one you're wedding too - doesn't this make the best sense?
