I don't know what the current song is but don't you think "we will rock you" would be awesome for earth?
As far as I can tell, the current one is 'cliffs of dover' by eric johnson. I guess cliffs = earth. To my ears it sounds sort of like a country-esque instrumental (ie, no words).
There are no advantages for having good songs right? If not I might have suggestions for several elements.
Here's a few other ideas for Earth's song (my new team^^).
Probably my favorite (light metal genre):
Samael - On Earth
It sort of goes with the banner ("you live on it") too. If you know the lyrics to On Earth, and listen to it a few times it grows on you and gets more and more catchy. It can be a bit hard to decipher at first so here's the lyrics:

Lyrics to On Earth :
Before we could talk we were singing
Before we could walk we were dancing
Life is short but not a day is lost
The world goes round and round
And we go on and on...

On earth, we're all
Dancing with the hidden tribe
Learning to move and fly
Touching the sky with our hands
Longing to love to understand
Dancing with the hidden tribe
Learning to move and fly
Touching the sky with our hands
Longing to love to understand
New York to Tokio
Melbourne to Budapest
Prague to Jaipur
Shangai to Montreal
Vancouver to Singapore
Sofia to Johanesburg
Hong Kong to St. Petersburg
On earth, we're all
Dancing with the hidden tribe
Learning to move and fly
Touching the sky with our hands
Longing to love to understand
Dancing with the hidden tribe
Learning to move and fly
Touching the sky with our hands
Longing to love to understand
