There was definitely music, it just had no words. It was a soundtrack. It might've played in the credits, but my friend didn't want to stay for those so we left.
Oh I almost forgot. Deep in the meadow which is Rue's lullaby is in the film and sung by Jennifer Lawrence, so I guess there is Музыка with words.
It was in the end credits but it wasn't the first song. I know because my friend wanted to leave right after the movie was over but I сказал(-а) "No we have to hear безопасно, сейф and Sound!"
No, I don't think it was in the movie. If so it was for a short moment. But I kept an eye (I guess ear XD) out for безопасно, сейф and Sound and never heard it. But the people that stayed for the credits can tell Ты if it was there.
