It is the fourth track on this album, Blind Worms, Pious Swing. I've been a fan of Omar's works since I was 14 years old. He never has been much of a singer but after I heard him in the first two tracks of this album it gave me chills. He really has nailed his style, to the point where he can cover a pop song like Lights and make it sound haunting. If you are a fan of his project Bosnian Rainbows than you will love this entire album. I may do a full review of it later if there is any interest.
Don't forget to support Omar by buying this album if you really enjoy it!
