Mistake is that one sad song that I really go back to. I don't know, for some reason it really has that appeal to me. I was totally blown away when this first came out and I really couldn't believe it at first as well that Yuri wrote the lyrics for this one. It's such a beautiful song and it really hit me home just perfectly.
You want to have that one song that really reflects you being hurt and being a fool in love, this is it.
