When you hear "You're from the 70s, but I'm a 90s b***h," on the radio or in a club, you’re likely to hear “I LOVE IT!” in quick response. The song by the Swedish DJ duo Icona Pop has become a must-play single at parties everywhere. The song isn’t just taking Germany by storm, though.

"Everywhere we go, we are immediately asked: 'Hey, are you the 90s b***h?' This line is really known by everyone," says Aino Jawo at the airport in Los Angeles.

Aino, 26, and Caroline Hjelt, 25, are based in the United States now but will be playing festivals all over the world this summer. "We are currently leading a perfect life," says a content Aino.

Annoyed Neighbors Turned Them Into DJs

The members of Icona Pop have a lot in common. They both come from Stockholm and even attended the same music school, but they didn’t meet until they went to the same party in 2009. That run-in turned into a lasting friendship.

"Eventually we were unable to have any more parties in our apartments because the neighbors constantly complained. So just decided we should be DJs," laughs Caroline. "At first we didn't see ourselves as DJs. We saw ourselves as people who played the music we liked. Eventually we realized that it was totally our thing and we went professional.”

Breakthrough Thanks to Diet Coke

The story unfolded quickly. Icona Pop had already released singles and albums that were successful in Australia and Sweden. It was at the start of 2013 that they had their breakthrough in Germany thanks to a TV ad for Diet Coke (known as Coca-Cola light in Germany and many other countries). In the ad, four young women dance their way through Berlin’s wildest clubs. The soundtrack for their night out: Icona Pop’s “I Love It.”

"We really didn’t expect this success. If your song is playing in an advertisement, it reaches people who don't listen to the radio. And thanks to the internet, lots of other people around the world have of course seen the advertisement," say Aino and Caroline.

Listen to 90s Songs for a Good Mood

There's no doubt "I Love It" puts the listener in a good mood. But what does Icona Pop listen to when they want to lift their mood? Here are their three favorites: "Boys and Girls" by Blur, "Hey Boy Hey Girl" by the Chemical Brothers, and Robin S. with "Show Me Love".

Is it a coincidence that all three of these songs are from the 90s? Probably not. Especially if you consider the most famous line from Icona Pop's song: "You're from the 70s, but I'm a 90s b***h."
