The music was stolen

Not only was the music not stolen, it was originally composed by Damon Dorsey. It's his own work. As with most music, similarities are inevitable. For example look at how similar Craig Richey's score for Friends with Money resembles stuff by Jon Brion. It happens all the time. However Dorsey has scored tons of work for films, and has a bachelors degree in music composition. You can find proof/more of his exact score at his website dmdorsey [dot] ]com].
