Cover art for Birds lyrics by Margot & the Nuclear So and So's

I'll take a shot at a bit of the meaning.

I think this song could be about people using what they think could be quick fixes. The whole let's have a party, let's have a baby sections go along with the idea of quick fixes. For some reason when people are unhappy they turn to partying, getting drunk and high. When people are having problems in a relationship they think having a baby will fix everything.

But in reality those things just make a bad situation worse. Let's make it evil.

I very much agree with your take. That's how I took it too. :]
