Wait & see the project file …

Thank you for the reply, i will search with your suggestion 
So do you think that the song will be release with the project file? I don’t think that song is property of Unreal Engine, so why they didn’t put the name in Youtube? is strange, it’s a violation of the copyright if the song isn’t produced by them
