Well, if you ask me "who is the composer", I would simply say, "I am the composer".
Indeed, I mixed some different musics into a single file using audio-editing software (and I also edited the musics a little bit). Some musics come from WW2 related animation, video, and some from WW2 games. You can hear the famous Jeff Wayne's music of The War of The World titled "The Fighting Machine" here (of course, it's been remixed).
I hope it doesn't violate any copyright law, does it?
