Jamie Campbell Bower isn't just an incredible actor, but he's also an amazingly talented musician. He, along with members of The Mortal Instruments Fandom have shown great interested in him having a song on the City of Ashes Soundtrack. If we're able to get a big enough petition, we can hopefully get him on the City of Ashes Soundtrack. It'd be great to not only have him act in the movies, but also contribute to the franchise musically as well.
