So I'm a little late to post this (It was supposed to go up Friday, but my upload kept failing), but whatever... The song is more about the season as a whole anyway... :D

Lyrics:

Six months without new episodes, but an awesome fanbase!
But we've kept busy with fanfics, comics, art, and even cosplays...
But the creativity's running out, and we need fresh shows to grow...
And even though a break was good, this wait is getting old...

I've listened to most every song
that the bronies have made
I've freed up space on my hard drive
Awaiting for the day.
I first converted, you see.
just before season 2.
I never had to wait so long!
I don't know what to do!

...I do.

Season Start-up, Season Start-Up!
Everypony give a cheer
Season Start-up, Season Start-Up!
'Cause Season Three is here!
'Cause Season Three is here!

An Epic villain at the start
The two-parter begins
Where the Mane Six are put to the test
But you can bet they'll win!
They'll get stuck fighting Celestia's battles
But that's just fine because they're more than capable!

Season Start-up, Season Start-Up!
Everypony give a cheer
Season Start-up, Season Start-Up!
'Cause Season Three is here!
Season Start-up, Season Start-Up!
'Cause Season Three is here!
'Cause Season Three is here!

More new songs to remake
Give it a brony take
Maybe more singing Applejack,
Rainbow, and Fluttershy

Another Luna episode,
possibly a sister fued?
Lyra, Bon-Bon, Scratch, Octavia,
There's just too much to choose!

Season Start-up, Season Start-Up!
Everypony give a cheer
Season Start-up, Season Start-Up!
'Cause Season Three is here!
Season Start-up, Season Start-Up!
'Cause Season Three is here!
'Cause Season Three is here!

Applejack needs way more screen time
She is the best pony!
Conflicts to build more character
It's just what she needs.
More Big Mac and Apple Bloom,
And their parents too!
So much untouched history
So much that you could do!

Season Start-up, Season Start-Up!
Everypony give a cheer
Season Start-up, Season Start-Up!
'Cause Season Three is here!
Season Start-up, Season Start-Up!
'Cause Season Three is here!
'Cause Season Three is here!

I know it's shorter than before,
But no need to dismay!
We'll fill the gaps with all our hearts,
It'll be truly great!
Together we create the magic,
Friendship the pony way!
Everyone belongs, so come on
Join the herd today!
Join the herd today!

Season Start-up, Season Start-Up!
Everypony give a cheer
Season Start-up, Season Start-Up!
'Cause Season Three is here!
Season Start-up, Season Start-Up!
'Cause Season Three is here!
'Cause Season Three is here!
'Cause Season Three is here!
