One - Aimee Mann

One is the loneliest number that you'll ever do
Two can be as bad as one, it's the loneliest number since the number one
'no' is the saddest experience that you'll ever know
Yes, it's the saddest experience you'll ever know
Yes, because one is the loneliest number that you'll ever do
One is the loneliest number that you'll ever know

It's just no good anymore since you went away
Now I spend my time just making thoughts of yesterday
(one by one)

Because one is the loneliest number that you'll ever do
One is the loneliest number that you'll ever know
One, is the loneliest number
One, is the loneliest number
One is the loneliest number that you'll ever do
One is the loneliest number, much worse than two
One is a number divided by two
