It's the song at the end of the episode, when Lauren and Lo are talking about that Spencer asked Heidi to move in with him.
It's like:
One breath, too late
And you're gone, for good
It's funny how far it seems
But what can i do, and what will i change?
when everything is strange
and why should i learn to fly
when i can just hide away
Isn't it strange ..
Help me, pleaaaaase!
