Who says disco is dead? Or that it can't be used to explain complicated news events, like the debt crisis that threatens to disassemble Europe as we know it. A number of eurzone-themed songs are making their way up the monetary charts.

Take, "The Euro Crisis Song," a funky little number courtesy of The Guardian, which starts this way:

"Portugal, Ireland, Greece and SpainWho's going to bail them out?"

But you've got to wait for the hook...

"They call you PIGSBut they don't understandYou're not the only onesTo spend more than you can ..."

Marketplace revived a different musical genre to explain the crisis — comparing the eurozone to a barbershop quartet, which only works if every member is singing. "When the baritone, bass and the tenor can all gather around Germany's lead, they form a quartet or a Eurobond that's backed up by the entire eurozone," Christopher Werth explained.

A quartet named Harmonious Rex sang:

"Every morning, every evening, got Eurobonds!Not much money, oh but honey, got Eurobonds!"

The Atlantic this week said the euro crisis is just like Carly Rae Jepsen's "Call Me Maybe."

"Neither will go away," wrote associate editor Matthew O'Brien. (In fact, the song is so irresistible NPR hosts and reporters recently took turns singing it.)

O'Brien then took on the crisis, line by line.

"It's hard to look right at you, baby.""Is there any doubt Carly Rae Jepsen is really talking about Spanish bank balance sheets here?"

And:

"I beg and borrow and steal.""Sometimes even the cryptic Carly Rae Jepsen speaks plainly. This is one of those times. The line above is clearly about Greece."

Last fall, Planet Money brought us the history of the European Union in a song called "European Union Wiz Me."

"France: You naughty boy you triedTo keep me occupied, mais ouiBut relations would be warma'If you snuggle up and form aEuropean Union wiz meGermany: I luff your perfumeFrance: Your GDPBoth: A european unionWiz/vith me!"

And Merle Hazard (his website says he's "the first and only country artist to sing about mortgage-backed securities, derivatives, and physics.") came up with the "Greek Debt Song":

"They borrowed shortAt a lower rateLike the Wall Street brokers we have grown to hate."

His musical analysis continues:

"Some say that Greece may drop the euro, the euro, the euroSo their products can compete.And if it still is not enough, not enough, not enoughMaybe they can sell off Crete."
