Chorus riff till the end


Careful when you open
it's easy to be broken
in the strangest fashion
you start a chain reaction
when you look my way
something's pounding away
And I wonder if I ever felt this before

and all this time oblivious to what you make so obvious
I can't believe I never noticed my heart before

You are reaching for something that is beating
I can't believe i never noticed my heart before
Over and again racing out of my skin
I can't believe i never noticed my heart before

At least it was never until I noticed you 
and your ways capture what I've misplaced
in the perfect fashion
Just watch my hearts reaction
This point of view is nothing that I'm used to
But I wont close my eyes cause they're onto you

And all this time it was staring me blind
I can't believe i never noticed my heart before

You are reaching for something that is beating
I can't believe i never noticed my heart before
over and again racing out of my skin
I can't believe I never noticed my heart before

at least it was never until I noticed you
Woah-oh
The only time I ever noticed my heart was when I noticed you-yeah
the only time I ever noticed my heart was when I noticed you-yeah
You-yeah, you YEAH!
1-2-3!

You are reaching for something that is beating
I can't believe i never noticed my heart before
Over and again racing out of my skin
I can't believe i never noticed my heart before

Till I noticed you-yeah
I noticed you-yeah
When I noticed you-yeah
I noticed you-yeah
That's the only time I ever noticed my heart before
