Does anyone else have a song which they share with someone else so everytime it comes on it's "Omg, it's our song"?

And also do you have songs which remind you of other people? Or is it only me =/?

Each one of the boys I have liked have a song that makes me think of them.
Maria Mena - Miss You Love (shared with Sofi)
Kelis - Millionaire (shared with Holly)
