I noticed tonight that the world has been turning While I've been stood here Dithering around Though I know I said I'd wait around 'til you need me I have to go I hate to let you down But I can't stop now I've got troubles of my own 'Cause I'm short on time I'm lonely, and I'm too tired to talk I noticed tonight that the world has been turning While I've been stuck here Withering away Though I know I said I wouldn't leave you behind But I have to go It breaks my heart to say That I can't stop now I've got troubles of my own 'Cause I'm short on time I'm lonely, and I'm too tired to talk To no one back home I've got troubles of my own And I can't slow down for no one in town And I can't stop now And I can't slow down for no one in town And I can't stop now for no one The motion keeps my heart running The motion keeps my heart running The motion keeps my heart running The motion keeps my heart running
