Sam Tsui feat. Lindsey Stirling, Sam Tsui & Lindsey Stirling heads up

The Sky looks blue to me
Yes i just couldnt see the writing on the wall
how could i know
I was about to fall
well here i go
Your smile was just a poker face
said I could never be replaced
I guess you told the light said we'll always be together you and I
but suddenly you say theres a tear
caught me unprepared
next time warn me before
I find my heart on the floor
Should have known that i dont like surprises
cause i'm still feeling it hard
caught me way off guard,
Why am I the last to know
Baby all Im asking for is
give me a heads up
wont you wont you give me a heads up
oh give me a heads up give me a heads up
before you tear me down
Too late it isnt fair
came out straight from out of nowhere
Dont even get a chance to play my part
come from behind and smash my fragile heart
You say its for the best
That way get it over fast
