Hi Everyone. Here goes:

This one's mostly a rock song, with a liiittle tiny touch of screamo. It's a male singing to a girl, I think he's talking to her through her window. He asked her to follow him out of the window (?) and hold his hand to fly into space and fly past the stars and the moon to be together in space?

Lots of space talk. Words I recall (in no particular order- sorry):
Atmosphere
Stratosphere
Stars
Moon
Gravity
Galaxy
Satellite
Hold/Take my hand
Fly
Sky
Window (?)
Together
Won't let you fall (?)

I barely heard it only once at a store and never again, but it was such a cool song that I'm still searching. Thanks!
