I really enjoyed this music from the movie "The Machine" (I think they play it in the end credits in the movie)... feels very "futuristic" to me. I could see something simmilar being used for maybe the start menu screen or something simmilar in the game. Maybe it's not "dark" enough for the game though, but I would still like it if you sometimes hear something simmilar in the game.
I would also like if some areas in the game maybe featured music similar to, or actually made by, artists like Marilyn Mansons. Not sure which song to show from Manson, seeing as Marilyn Manson is probably my nr1 favorit artist out there, which means that there is a huge amount of songs I like a lot but have a hard time just pick one. So I decided to make it random, added all my Manson songs to my winamp, put on random, and pressed start, this is the one it picked. I really enjoy the instrumental part in this song, very rythmical heavy and dark and... awesome. XD
Then of course there is the entire Cyberpunk album by Billy Idol, the second CD I ever bought in my life, totally ahead of it's time (it flopped pretty hard due to it unfortunatly), and totally awesome.
This is the link to a playlist with all the 19 tracks in order. Of course, not all 19 tracks are songs, only 13 of them are, the rest are an intro, intermissions, and an outro.
