Flashlight by Jessie J (Soundtrack of Pitch Perfect 2)

Hmm... The current hottest song? I'm gonna flash it in your eyes! (horrible pun, I know, sorry)
Enjoy the song, sing along, do whatever :)

Lyrics:

When tomorrow comes
I'll be on my own
Feeling frightened of
The things that I don't know
When tomorrow comes
Tomorrow comes
Tomorrow comes

And though the road is long
I look up to the sky
And In the dark I found, I stop and I won’t fly
And I sing along, I sing along, then I sing along

I got all I need when I got you and I
I look around me, and see sweet life
I'm stuck in the dark but you're my flashlight
You're gettin’ me, gettin’ me through the night
Can’t stop my heart when you shinin’ in my eyes
I can’t lie, it’s a sweet life
I'm stuck in the dark but you're my flashlight
You're gettin’ me, gettin’ me through the night
Cause you're my flash light
You're my flash light, you're my flash light

I see the shadows long beneath the mountain top
I'm not the afraid when the rain won't stop
Cause you light the way
You light the way, you light the way

I got all I need when I got you and I
I look around me, and see sweet life
I'm stuck in the dark but you're my flashlight
You're gettin’ me, gettin’ me through the night
Can’t stop my heart when you shinin’ in my eyes
Can’t lie, it’s a sweet life
I'm stuck in the dark but you're my flashlight

You're gettin’ me, gettin’ me through the night
Cause you're my flash light
You're my flash light light light, you're my flash light light light You're my flash light light light light light ohhh
I got all I need when I got you and I
I look around me, and see sweet life
I'm stuck in the dark but you're my flashlight
You're gettin’ me, gettin’ me through the night
Can’t stop my heart when you shinin’ in my eyes (shinin in my eyes)
Can’t lie, it’s a sweet life
I'm stuck in the dark but you're my flashlight (you're my flashlight)
You're gettin’ me, gettin’ me through the night
Cause you're my flash light
You're my flash light, you're my flash light
You're my flash light light light
You're my flash light light light
You're my flashlight
