She won't let me buy her jewelry. She don't want things that she can keep. She wears wild flowers in her hair. Then throws them to the sea. She's the beginning and the end of me but. Chorus:. She's a mystery. My most beautiful regret. I will never understand her. She's a mystery. I still don't know what to call her. She says that words don't mean a thing. She changes her name every day. And lies all the time. I feel lucky to call her mine. Chorus:. She's a mystery. My most beautiful regret. I will never understand her. She's a mystery. The only promise I can keep. Even in my dreams she ruins me. She's anything in the world. That you cannot explain. But when she throws me a smile. It's like fire in the rain but. Chorus:. She's a mystery. My most beautiful regret. I will never understand her. She's a mystery. She's a mystery. There's no defense. It's innocence. But she won't let you see. 'Cause she's a mystery.
