Even if you don’t live in Europe, you don’t want to miss out on the fabulousness that is Eurovision. Actually, especially if you don’t live in Europe.

Here’s what you need to know about Eurovision 2016 and its final Saturday evening in Stockholm, Sweden:

What it is

The Eurovision Song Contest is an annual competition that pits singers from participating countries against each other. To be eligible, contestants must be from one of the member countries that make up the European Broadcasting Union.

Forty-three countries were supposed to be represented this year, but Romania went and got itself expelled for reportedly failing to pay outstanding debts. Each country has a contestant who sings an original song and attempts to bring home the glory.

It’s quite theatrical. Think the Oscars, Grammys, Tony Awards, “American Idol,” “The X Factor” and “America’s Got Talent” all rolled into one – and then triple that.

How it works

Viewers from participating broadcasters can vote for their favorite song but not for their own country. The votes can be cast via telephone, SMS or using the official app.

There is also a jury of professionals. Votes from the professional juries and viewers used to be combined and then counted as 50% of the final score.

But according to Eurovision’s site, “this year the professional juries and televoters from each country will each award a separate set of points from 1 to 8, 10 and 12.”

“This now means the top 10 countries in both the jury and televote will receive points, adding a new level of excitement for hundreds of millions of viewers in Europe and beyond,” the rules on the site say.

It gets political

If some folks are to be believed, Eurovision can be like a musical “House of Cards.”

Block voting, nationalism and a settling of old scores (“If you think I’m voting for you after you all invaded our country a few years ago, you are nuts!”) have long been accusations when it comes to Eurovision.

In 2003, the UK’s stance on the Iraq War was blamed for the incredibly poor showing of British pop duo Jemini.

Speaking of politics, this year organizers are dissuading contestants from getting political with their song choices.
