Some company is overdue?

I saw Frozen, a Big Box Office Hit in Korea weeks ago.
One of those pleasing songs was 'Do you want to build a snowman?', which I liked a lot.

This is part of the lyrics : Some company is overdue.
Not knowing its exact meaning, I looked up my dictionary to see what 'overdue' is.

Overdue is, my dictionary says, 'not appearing or presented by a stated, expected, or required time.'

Then, does 'some company' here refer to Elsa, Anna's sister
and did Anna mean to say 'You're not appearing when expected'?

Dang. It's so tough to fully explain what I want to know with ease.
I definately should practice writing more and more.

Anyways, would any of you please help me figure out what the sentence mean and when it is usually used in a daily situation?

Thanks.
