Cover art for Top Five lyrics by Tokyo Police Club

I believe it's; "Born 1983..." and "'odd numbers like '15' don't sound like something I would use, 'cause from now on we will always be a pair, and I won't try to pluralis(z)e as long as you're still there."

He's always talking about time in general........past, wasted, spent, lost......etc.

yeah, that makes more sense. made the corrections, thanks!

Having another listen to a live version, I think he says ""Hop on the back, sweetheart!" doesn't sound like something I would say."
