The lyrics go like this:

In the new time

Despite the punishments

We are grown up,

We are attentive,

We are more alive

To help us, to help us, to help us

In the new time,

Despite the dangers

Of the most brute force,

Of the frightening night,

We are in the fight

To survive, to survive, to survive

So that our hope

Is more than vengeance

That it always be a path

That is left as an inheritance

EDIT: the original translation I posted shifted stuff around and (I think) made people miss the connection between the verses 'in spite of dangers / of the most brute force' which would kinda make it seem that force was maybe being glorified from then on. I also changed the title to make it more explicit.

Basically it's a song about an impending general improvement that was hoped for after the fall of the brazilian military junta. Parallels being likely drawn with the end of unipolarity.
