Tonight I started loving one moment in time lyrics. I listened repeatedly. What do you think about it? and how many English do you got from this YouTube. I have few words I don't understand like destiny and eternity. I want one moment in time, I rise and fall, yet throught it all, that much remains. Please tell me what do these sentences mean?
