I'm looking for the music that plays during the scene where (warning: major spoiler)Rikiya dies.
If anyone knows what it's called, or where to download it, or any information about it, then please post what you know. It would be very helpful.
I've downloaded the Yakuza 3 gamerip, (http://forums.ffshrine.org/f72/ryu-ga-gotoku-yakuza-4-adx-aix-84846/#post2334523) but unfortunately it doesn't seem to have it.

You can listen to it here, (http://youtu.be/B0mW0w8VRvw?t=5m20s) but be warned that this is a major spoiler in the game.

Does this song play during the end credits as well? This is a guess, I didn't check your link.
