The lyrics are better than non francophones might suspect:

When we say study, it means work,
When we say work, it means money,
When we say money, it means spending
When we say credit, it means debt,
When we say debt, it means bailiff,
We agree to being in deep sh*t
When we say love, it means kids,
When we say forever, it means divorce.
When we say family, we say grief, because misfortune never comes alone.
When we say crisis, we talk about the wold, famine and then third world.
When we say tiredness, we talk about waking up still deaf from sleepless night
So we just go out to forget all our problems.

So we just dance

Seriously, just discovered this, and I can't remember my semester of Francais, but this is up there with better LCD Soundsystem, lyrically.

So you say that it�s over because the only thing worse would be death.
When you finally think you�ll make it, there�s more and more!
Ecstasy means a problem, problems or just music.
It grabs you by the guts, it takes hold of your head and then you pray for it to end.
But your body is no heaven so you block your ears even more.
And then you yell even louder and it goes on�
So we just sing
Lalalalalala, Lalalalalala,

And then only when it�s over, then we dance.

That was the first song I've ever heard that was able to incorporate bits of several other songs w/out it turning into one of those lame mash-ups.

That was.... awesome.
