《Astronaut》的歌詞如下：
女：
I'm an astronaut in your gravity
Trying to float my heart and float away
I'm an astronaut in your atmosphere
Trying to break my fall, break the day
男：
I'm a space between your stars
A shooting star, a wish that's far
I'm a satellite, I'm your satellite
Trying to find a way, to stay
女：
Oh, I'm falling deeper into you
Oh, I'm trying to hold on to you
Oh, I'm an astronaut in your gravity
Trying to float my heart and float away
男：
I'm a satellite in your sky
A shooting star, a wish that flies
I'm a satellite, I'm your satellite
Trying to find a way, to stay
合唱：
Oh, I'm an astronaut in your gravity
Trying to float my heart and float away
Oh, I'm an astronaut in your atmosphere
Trying to break my fall, break the day
Trying to break my fall, break the day
Trying to break my fall, break the day
女：
Now I know how hard you burn up in the dark (burn up)
All for the light of your fire that I thought I was floating above (that I thought)
I got so caught up up in my fantasy (got so caught up)
So lost up in up your gravitational pull (got lost)
Astronaut so far away (got so lost)
In space, how long before we break up today? (we break up)
Astronaut, yeah, we fall apart (Astronaut)
Oh, we fell for the dark, fell apart today (Astronaut)
男：
And I thought you were something out of reach (out of reach)
A shooting star that burned up in the night sky (burned up)
Now I see it was all just illusion (was just illusion)
I was caught up up in my fantasy (caught up)
But now I'm lost up in your gravitational pull (lost up)
Astronaut so far away (lost up)
Oh, now we're breaking up today (Astronaut)
Astronaut, yeah, we fell apart (Astronaut)
Oh, we fell for the dark, fell apart today (Astronaut)
(Astronaut)
Oh
(Astronaut)
Now we're done
(Astronaut)
