I keep a playlist of instrumental music for themes and characters. When I read your comment it reminded me of the track I'm saving to use as my steampunk detective's theme song.
That music is cool! One more to my epic music collection on youtube. Now let me show you some steampunk music for you get even more inspired: This video is an intro from a video game but look for this: Arcanum of Steamworks and Magick Obscura soundtrack. You will devour this game soundtrack in no time with true steampunk music at your side. And I look forward to that story.
For My Amazing Man @Cave Troll Starship-Nothing's Gonna Stop us Now: I know it's cheesy, but oh well.
