I like the 6th song best, the shared lyrics is the following:

Pretend you're happy when you're blue
It isn't very hard to do
And you'll find happiness without an end
Whenever you pretend

Remember anyone can dream
And nothing's bad as it may seem
The little things you haven't got
Could be alot if you pretend

You'll find a love you can share
One you can call all your own
Just close your eyes, she'll be there
You'll never be alone

And if you sing this melody
You'll be pretending just like me
The world is mine, it can be yours, my friend
So why don't you pretend?

[Musical Interlude]

And if you sing this melody
You'll be pretending just like me
The world is mine, it can be your, my friend
So why don't you pretend?
