Those things are important to many relationships. And being into knowing those things about someone will indeed bring closeness.

I don't want to sound like I'm going to take away from that. But I would like to offer an option.

I'd like to think that those favorite things change over time. So why would I want to lock my partner into a pattern and not let him/her grow? Maybe the two people can get new songs that renew and make their relationship even better. Let's not let our relationships get stale and passionless. Make them better. That's what we all want, isn't it?

That is what I mean, if you continue to learn little things like this and know that as time goes on it will change, that everything can change in a realtionship. That we need to constantly learn about the person we are with, but starting with the simple things can let the other know they are listening.

I don't want to know "everything" about my partner, I want to spend my life learning. Having a check list that defines a relationship is limiting to that relationship. How about knowing yourself, as most people don't. Do you know why that is your favorite color, song, shirt, etc.? If you are weak in your self knowing, then you will be weak in knowing the other. It's like asking yourself what do you bring to the table, what quality and value of self are you contributing to the relationship? Do you know?

If you want to find out about all those things, play a little game with him. You know those email surveys you get in your inbox every once in a while from friends? The ones that ask you, like, 50 random questions? Send one to him if he has an email, or spend the night playing an inquisitive verson of 20 questions. I always find that it's also a good conversation starter as well, and you'll learn more about him and his personality that way. Do it on a lazy afternoon or during a road trip or something.

I always thought those were important but when I fell for my partner I barely knew much about him just a few things that made me fall harder with everything I found.
We have been together for a couple of years now and we are still learning new things about each other everyday!!
We don't have a 'song' but the memories that come back to me with different song are enough!!
So I don't think they are important anymore as long as you know what they are like personality wise and maybe habits.

I agree and would add it's more important that we know these things about ourselves
