song artist and lyrics

Hello! I could totally use some help on this. There's two songs that I have a question about. The first one I have all the lyrics, but i just don't know who sings or it what it's called:

Oh Lord, You have turned
My mourning into dancing
Over and over and over again
Oh Lord, You have turned
My sorrow into joy
Over and over and over again

You have been my shield
The lifter of my head
You are my joy
You are my joy
I will always worship
I will always worship you for you
You are my joy
I will always worship
I will always worship you for you
you are my joy
you are my joy

You turned my mourning
Into dancing
Over and over
Over and over and over again

Over and over and over and over
Over and over and over and over again

WOW! This is a long post. My apologies.
Secondly, there's a song that is called "Joy Joy Joy". I don't know who sings it though. I can't remember all the lyrics, but I remember some.

Joy Joy Joy
Joy Joy Joy
Whom shall I fear
He is my strength
He is my shield

Verse 2
No weapon formed against me shall ever prosper
*something something* whom shall I fear
I know there's a host of angels
Encamped around me
*something something*

Vamp
Joy in the battle
Joy in the journey

Any help is by far more than what I have.

That song is "My Joy" by Alvin Slaughter it is on his CD " The Faith Life"

The first song is by Israel Houghton but I don't know the name of it.

It is a great song. I love it!

Hope this helps somewhat.
