I'm sittin' in my hotel room The checkered bathroom, birthday blue I'm wonderin' what you're goin' through today I'm feelin' like a plastic plane My neuropath will start today So just the thought of you is all it takes I keep your photo on my wallet too It's all I need to re-adjust my mood Oxytocin keeps me goin' Serotonin, keep it flowin' What would my life be like without my little spark? What would my life be like? I'd be left in the dark I'd be left in the dark I knew it when I heard your voice Not even like I had a choice Somebody else is havin' sex next door I listen to the random sounds A busy heart, a quiet town I'm trippin' on room service on the floor I keep your photo on my wallet too It's all I need to re-adjust my mood Oxytocin keeps me goin' Serotonin, keep it flowin' What would my life be like without my little spark? What would my life be like? I'd be left in the dark I'd be left in the dark Talkin' to the mirror Until I can see you again Oxytocin keeps me goin' Serotonin, keep it flowin' What would my life be like without my little spark? What would my life be like? I'd be left in the dark
