I have both the US & Jp versions. The Jp version(The Kick Boxing) just has some fairly bland renditions of the same songs. I just went & ripped the disc, here's what's on it:
Track 1: Standard Jp warning
Track 2:data
Track 3:Introductory cinema with a guy probably talking about the long history of kick boxing or something
Track 4:Sounds like the exact same as Track 3
Track 5:Another Cinema, this one is a guy doing various moves, & says in bad English "Hey you, come one, ret's fight!"
Track 6:same as Track 5
Track 7:That Rocky'esque victory theme
Track 8:Ending Cinema/Credit theme as far as I can tell without going & beating the game, I can't recall the US versions theme, since I only beat it once but I assume this is the same song
Track 9:Rejoice! For this is the same as Track 8, but now louder! Yay!
Track 10: the High Score theme
Track 11:Some sort of victory theme, sounds familiar, maybe it's when you you've beaten Panza?
Track 12:Some clapping & cheering
Track 13:Differnt clapping & cheering, & some data information at the end of the track
