Can't Stop Now lyrics

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 till 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
[ Lyrics from: http://www.lyricsmode.com/lyrics/k/keane/cant_stop_now.html ]
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
