Here's a nice cheery song (in terms of the melody at least) right before temperatures plunge for the rest of the month.

Club 8 - Hope for Winter

I was wrong
You were right
A day in December
Can be so nice

Wishing and hoping
Just won't do
I won't come
Closer to you

Let's all hope for winter
Winter cools us down
The brightness of springtime
Makes you, makes me
Feel down

All at once
Or nothing at all
I couldn't help
Feeling so small

In the end it's all the same
I won't come
Closer to you
I know I want to
But could I really do
When decisions are made by you

Let's all hope for winter
Winter cools us down
The brightness of springtime
Makes you, makes me
Feel down
