Does anyone have the mp3 for kaiba's little theme that plays in the background of the show sometimes? Usually they play it when he's dealing with kaibacorp or soemthing. Weird request but if anyone has it or knows where to find it please reply.

Yeah, it's actually a song by the name of Duel Madness:

That should answer. No, unfortunately, they haven't released an instrumental version.

no that's not what i'm looking for, what i want is just the music part

The song is on the CD, Yugioh Music to Duel by and is called "Summon the Dragon"- the entire song is instrumental and there are several parts in there which the show takes and uses for different things kaiba does. Hope that helps, and I believe it is on the site too.

Music to Duel By is stuff from Season 1 - and Kaiba's theme is played Season 2 onwards if I am not mistaken. Summon the Dragon has been used for Ra as well.
