The heart may freeze, or it can burn. The pain will ease, if I can learn.

Mimi: The heart may freeze, or it can burn.
        The pain will ease, if I can learn.

        There is no future, there is no pass.
        I live this moment as my last.

[Rent, No Day But Today, 2005]

Satine: You'd think that people would have had enough of silly love songs
Christian: I look around me and I see, it isn't so

Satine: Some people want to fill the world with silly love songs
Christian: And what's wrong with that. I'd like to know
