I hope I'm not the only fan of the Detective Conan series and it's Jazzy music in the background, especially when ever the criminal is discovered. So, I went surfing about and find out that it's rather hard to find.

So, I was wanting to know if anyone knew where to download them.

It is possible to find, the song you speak of when they find out who the killer/criminal is is called "Showdown" ... i have two different versions of it, the soft version and the skyscraper version. Awesome track ... :-) Youtube what I just told you some of the videos have links brotha'!
