鋼彈G的主題曲歌名為《Blue Drops》，以下是歌詞：
Every day I fall for my dream
So please don't make it stop
Feels like a secret so don't tell a soul
This feeling is my weapon
(Verse 1)
All my life I've been searching for
A spark to light up my darkest nights
Take control of the wheel of my fate
Oh yeah, it's my blue drops
(Pre-Chorus)
Don't let go of your dreams
Even if you fall down
You'll rise up like a phoenix from the flames
It's the only way to get the best of you
(Chorus)
Oh blue drops, keep falling down
Keep me up, give me hope again
Oh blue drops, they never stop
Keep on dreaming, keep on chasing your dreams
(Verse 2)
Can't stop now, it's all or nothing
A universe waiting to be discovered
Just believe in your destiny
Oh yeah, it's my blue drops
(Bridge)
Believe in yourself, there's no limits
No need to doubt yourself anymore
Follow your heart, that's what we do
That's how we rise up from the blue drops
(Chorus)
Oh blue drops, keep falling down
Keep me up, give me hope again
Oh blue drops, they never stop
Keep on dreaming, keep on chasing your dreams
(Outro)
Blue drops, keep falling down forever (keep on dreaming)
In the end, you'll find your own blue sky (keep on chasing your dreams)
