I'm including the Amalee cover, as I consider it to be semi-official, as she was the English VA for Uta (the character singing the song in the movie, though the songs were not dubbed), and she is using the official sub lyrics in her cover.
We can choose the way of our future
Try a brand path, if I change the world, if I change the world…
Say goodbye to everyone who stands against us
No one has the power to stop a change that comes through music
No, you can’t stop magic
Close your eyes and you can see the future before you
Every note I sing is bringin’ you closer to your purpose
Once your there don’t let go
You wanna play a real game, unfurl the chain
Melody strung out like we’re walkin’ on a tight rope,
Don’t wanna cry, don’t wanna try, wanna forget
Just let me live inside a dreamland, Wanna be free!
And let a brand new era dawn, I know that we can
Create a New World!
We can choose the way of our future
Try a brand path, if I change the world, if I change the world
This boundless music brings transformation, messages in song reach even further
This dream will come true, “I believe in you”
Say goodbye to everything that’s weighing you down
Transcend beyond reality to colorful worlds of music
We need to keep on rising
Close your eyes and take my hand we’re runnin’ together
We don’t have to live like this, I know we can all do better
I sing for liberation
You wanna play a real game, unfurl the chain
Melody lighting up the path to new horizon
Don’t wanna try, don’t wanna cry, wanna forget
Just let me live inside a dreamland, wanna be free!
And let a brand new era dawn, I know that we can
Create a New World!
We can choose the way of our future
Try a brand path, if I change the world, if I change the world
This boundless music brings transformation, messages in song
Reach even further, reach even further. A New Genesis
A New Genesis

I see this song as a meta-song, improving the effects of the next song used, so long as that song is one that causes changes or transformations in the world (that is, not personal shapeshifting or similar), and that Doug truly believes said changes would improve the world. This song would improve the changes caused by the affected song, boosting, range, durability against disruption, and permanence, while also lending the changes made an impression of "too good to be true." The larger the changes the boosted song would have made without the boost, the bigger the boost will be.
