Best Final Boss Music

BIS, but I think he already have a topic for this.

Not sure though.
 
NSMBWii comes to mind but I'm gonna have to go with Super Mario 64.
 
The final bosses of Bowser's Inside Story are:

Dark Bowser and Dark Fawful.

D'oh, how could I forget this one! Galaxy and Galaxy 2 had epic music.
Yeah, I agree. I would have loved to see Galaxy 1's final battle song make its way into Brawl.

Also, Smithy's theme songs were epic, especially the second one.
 
I wouldn't know where to start. Bowser's 1st phase music from NSMB Wii sounded neat though.
