Juliana, talking about the track Suck It Up to Morgan Enos for a Grammys article:
"Suck it Up" is more specific to the idea of a creative person—an artist—going to a bank and trying to get a mortgage. This whole society is based on certain things: marriage, cohabitation, capitalism, consumerism, and also including homeownership. People are bred to believe that owning a home is something everyone should aspire to.
But it's not for everyone; that's one thing. If you're the type of person who doesn't have a weekly paycheck, no matter how much money you have, it's going to be difficult for the system to approve you for a big loan like that, because you don't have a steady weekly paycheck. That's exactly what the song is about.
It's kind of like "Mouthful of Blood" in the way that the system doesn't allow for nuance in speech or thought. Also, the financial system doesn't allow for nuance in ways of living. You can't just call and have a conversation. They punch your data into the computer, the algorithm feeds it back in numbers and you either cut the mustard or you don't.
The interview includes Juliana's thoughts on all 10 songs from Blood, and therefore well worth a read.
