My life was so simple when I was just living for me Didn't know I was missing, drumming to my own beat But if life is a song, what's a song when there's no harmony? Then you came along and you showed me how good it can be When you love a girl It will change everything, rock your whole world When all of a sudden She's all that you want and all that you need It makes you so strong, makes you weak in the knees When she smiles, yeah, you'd do anything Lay down your life in the blink of an eye 'Cause no matter the cost You know you'd walk through fire for her When you love a girl I ask myself now, how did I ever do this alone? 'Cause since I've been holding you I never wanna let go 'cause I'm home Yeah, without you, my heart is a half, it could never be whole And I couldn't settle for less, baby, now that I know When you love a girl It will change everything, rock your whole world When all of a sudden She's all that you want and all that you need It makes you so strong, makes you weak in the knees When she smiles, yeah, you'd do anything Lay down your life in the blink of an eye 'Cause no matter the cost You know you'd walk through fire for her When you love a girl Ten tiny fingers, ten tiny toes Babe, ain't it crazy the way love can go? She's got our hearts in the palm of her hand I guess now we both understand When you love a girl It will change everything, rock your whole world When all of a sudden She's all that you want and all that you need It makes you so strong, makes you weak in the knees When she smiles, yeah, you'd do anything Lay down your life in the blink of an eye 'Cause no matter the cost You know you'd walk through fire for her When you love a girl When you love a girl
