You wonder why I love you, there was never pressure Easy as I want to, there's just no one better You think it's calculated, baby, I'm just not that clever Never And what could I say? I knew that it would go this way Or could you blame it on fate? I couldn't let it just escape Now at the end of our days, I'll run back thoughts of you Thoughts of you keep me up at night Up at night, up at night Thoughts of you keep me up at night Up at night, up at night Thoughts of you keep me up at I think about all of the ways you turn me on (turn me on) And my bed gets lonely whenever you're gone (whenever you're gone) And baby, I'm a wreck without you All I do is fantasize about you ('bout you) You're the light of my life, yeah, I mean it Girl, you got what I want, what I needed And even when the sun don't shine I'll be right by your side Holdin' you tight (you tight) And when you feel like nobody cares I'll be right there to remind you that You keep me up at night Up at night, up at night Thoughts of you keep me up at night Up at night, up at night Thoughts of you keep me up at And what could I say? I knew that it would go this way Or could you blame it on fate? I couldn't let it just escape At the end of our days, I'll run back thoughts of you Thoughts of you keep me up at night Up at night, up at night Thoughts of you keep me up at night Up at night, up at night Thoughts of you keep me up at Baby, the thought of you You keep appearin' in my dreams, huh-huh
