A bright song to cheer you up when you're... well, a bit tired of it all.

I love the video :)

I'm not about to give up
Because I heard You say
There's gonna be brighter days
There's gonna be brighter days

I won't stop, I'll keep my head up
No, I'm not here to stay
There's gonna be brighter days
There's gonna be brighter days

I just might bend but I won't break
As long as I can see Your face

When life won't play along
And right keeps going wrong
And I can't seem to find my way
I know where I am found
So I won't let it drag me down
No, I'll keep dancing anyway

I'm gonna move (move)
I'm gonna move (move)
I'm gonna move (I'm gonna move)

I've got to hold it steady
Keep my head in the game
Everything is about to change
Everything is about to change

This hurt is getting heavy
But I'm not about to cave
Everything is about to change
There's gonna be brighter days

I just might bend but I won't break
As long as I can see Your face

When life won't play along
And right keeps going wrong
And I can't seem to find my way
I know where I am found
So I won't let it drag me down
No, I'll keep dancing anyway

(I'm gonna move)
No matter what may come
Gotta move to a different drum
No matter what life brings
Gotta move gotta move to a different beat

No matter what may come
Gotta move to a different drum
No matter what life brings
Gotta move gotta move to a different beat

I just might bend but I won't break
As long as I can see Your face

When life won't play along
And right keeps going wrong
And I can't seem to find my way
I know where I am found
So I won't let it drag me down
No, I'll keep dancing anyway

When life won't play along
And right keeps going wrong
And I can't seem to find my way
I know where I am found
So I won't let it drag me down
No, I'll keep dancing anyway

(I'm gonna move)
No matter what may come
(I'm gonna move)
Gotta move to a different drum
(I'm gonna move)
No matter what life brings
(I'm gonna move)
Gotta move gotta move to a different beat

ABOUT TO= If you are about to do something, you're going to do it now, at this moment:
- Stop! You're about to step on a banana skin!
- Look, she's about to open her present!
- Hurry up, I think it's about to rain, I felt a raindrop on my nose.

GIVE UP= Surrender, stop trying.

YOU= God (that's why we use a capital letter)

GONNA= (coll.) Going to (future)

BRIGHTER= Happier.

I'LL KEEP MY HEAD UP= I won't get depressed and I won't feel useless.

I'M NOT HERE TO STAY= I'm not going to feel bad forever.

BEND= If something straight bends, it changes from a straight line or position to a curve, in this case because you put something very heavy on it (life's problems and suffering)

AS LONG AS= If.

WHEN LIFE WON'T PLAY ALONG= When things are not the way you want them to be.

DRAG ME DOWN= Make me sink (figuratively here), make me break down, depress.

HOLD IT STEADY= Keep it securely in place.
"it" might refer to his head (he mentions it in the next line). I guess he means that if your troubles are trying to "drag you down" (has he said earlier), he must try to hold it steady and don't let himself to be drag down into despair. Sort of.

KEEP MY HEAD IN THE GAME= Focus on life or on changing my life.

IS ABOUT TO= We use this phrase to talk about near future, something that is going to happen very very soon:
- Run away! It's about to explode!
- Let's go home, quick, I think it's about to rain.

THIS HURT IS GETTING HEAVY= This pain / this suffering is growing stronger.

CAVE= When a flat surface bends down because something very heavy is on top of it and it may finally break (cave in). Here, it is a metaphor for breaking down and get depressed and paralyzed by suffering.

NO MATTER WHAT MAKE COME= I doesn't matter what may happen in the future (I'm going to change my life no matter what the future may bring)

GOTTA= (coll.) I've got to, I have to, I must.

BEAT= rhythm

This is an inspirational song to cheer you up when you're feeling down. Dance here is a metaphor for living life fully while enjoying it. But if you're having a hard time, how can you bright up and be happy? Well, you sure need to make a big change in your life, and that's the singer's resolution:

I'm gonna move

So if your life is not working, change it. But how?

Gotta move to a different beat

And what new beat is that? Well, the beat of love. Bring love to your life and everything will get better, and we're not talking about finding a lover, we're talking about Love, with capital letters, the only force that can make your life full and worth living. The power of love will give you strength during the bad times.

This hurt is getting heavy but I'm not about to cave

In the middle of all that pain one big hope takes shape:

So I won't let it drag me down
No, I'll keep dancing anyway

Everything is about to change
There's gonna be brighter days.

But where did he get all this hope that makes him want to change his life?

I just might bend but won't break
As long as I can see Your face

Whose face is it? God's face, of course, the source of all love. To see God's face in this life, is to be able to love abundantly.

So the message of this song is: if your life is hard, change it; learn how to love and everything will get better.

Note: if you read the lyrics carefully you could say that all the song is talking about love, but about the love of a woman. The thing is that MercyMe is a Christian band who only sings Christian songs, and the band leader is a pastor, so there's no controversy about whose love he is talking about, but anyway, believer or not, love is always love, and that's the fuel you need in your life.
