For a few weeks this spring, Sweden's most played song "The Cat in the neighborhood" was by 16-year-old rapper Einár. Nils Grönberg, whom he is really called (Einar is the middle name) lives everyday at an HVB home in Dalarna. But after the success, he tours almost every week, he says.

One of his role models is Sebastian Stakset - the former gangster rapper and the cartel member who switched tracks in life after finding his faith.

- I have become stable and strong in my new life and then it is easier to come in and help and support where needed. Right now you are under LVU and about to be free, says Sebastian Stakset and looks at Einár.

- And I think you should see that when he has had a career and has support around him, it is better to be free. He is not going back to any LVU or SiS or anything like that.

Then reported the baby leg

In their song "Mother Forgive", they ask their mothers for forgiveness for all the worries they have had to endure during their sons' lives. It came about when Einár posted a picture of his mother on Instagram and Sebastian Stakset called him.

- I have had problems in life that have caused my mother to feel ill or feel stressed. So it fitted. I thought it was a good song and so we just drove, says Einár.

- When you live a life in crime and drugs, there is always a mother who cried at the trials, at Soc and at the principal's talks, says Sebastian Stakset, who got the idea for the song.

But they met for the first time, much earlier. They remember a meeting in Enskededalen, where Einár was raised.

- I remember when he was tiny and came and rapped. We thought, “He's better than us already, and he's nine, ten years! what's going to happen to him? ”says Sebastian Stakset.

Tradition of mother's tributes

Einár started listening to Sebastian Stakset's previous group Cartel as a child.

- There was a lot of suburbs here and there but there was also a purpose with all the songs. You heard it was real, it came from something real, it wasn't a movie where everyone was an actor. And that's what has shaped my rap as well, to run as you are, says Einár.

With "Mommy sorry" they join a tradition of mum shelves in hip hop. But it is far from all women praised in rap texts.

- There is a lot that is said in rap that you should question why you say, thinks Sebastian Stakset, and continues:

- When I was living old life you had a jargon and a language, but I try to think now that all women ... I have daughters too, so I think a little differently now than when I was young.

Einár believes that hard language affects all groups.

- It is very much a stamp on one's self, and one forms it against another. "He belongs to the pounds", "she belongs to the whores", "he the impetuous". Living such a life is not the worst thing to call a whore.

Is mom always more important than dad?

- I have the best dad in the world and he also has a good dad, says Sebastian Stakset and nods to Einár.

- But there is a special bond between father and daughter and between son and mother, that's all, Stakset concludes.
