Jala has millions of views on Youtube and he is the most popular figure among those who represent Bosnia this year. I'm not into this kind of music so I was not familiar with his work, but he is really popular. Also, he is quite big in Serbia.
I think BHRT did a good decision with his engagment although many Eurovision fans hate that rap part. I might work good with televote, I don't know...
This is such a strong semi final, I believe Bosnia will go through, but also I wouldn't be surprised if they fail.
