What is it about his voice that just makes you feel so much better?

I've been feeling not quite myself the past few days. But I listen to Josh and it seems like everything is better, even if it's just for a moment. But I especially listen to these 2 songs.

SMILE

Smile though your heart is aching
Smile even though it's breaking
When there are clouds in the sky
You'll get by
If you smile through your fear and sorrow
Smile and maybe tomorrow
You'll see the sun come shining through for you

Light up your face with gladness
Hide every trace of sadness
Although a tear may be ever so near
That's the time you must keep on trying
Smile what's the use of crying
You'll find that life is still worthwhile
If you just smile

When there are clouds in the sky you'll get by
If you smile
And maybe tomorrow
You'll see the sun come shining through for you

Light up your face with gladness
Hide every trace of sadness
Although a tear may be ever so near
That's the time you must keep on trying
Smile what's the use of crying
You'll find that life is still worthwhile
If you just smile

You are Loved (Don't Give Up)

Don't give up
It's just the weight of the world
When your heart's heavy I
I will lift it for you
Don't give up
Because you want to be heard
If silence keeps you I
I will break it for you

Everybody wants to be understood
Well I can hear you

Everybody wants to be loved
Don't give up

Because you are loved

Don't give up
It's just the hurt that you hide
When you're lost inside I
I'll be there to find you

Don't give up
Because you want to burn bright
If darkness blinds you I
I will shine to guide you

Everybody wants to be understood
Well I can hear you

Everybody needs to be loved
Don't give up

Because...you are loved

Don't give up
It's just the weight of the world

Don't give up
Everyone needs to be loved

You are loved
