Me too. I like the escape from seawall, city combat, the install music and the Spider Robot battle theme. I like the tracks that are played online especially the 1 minute before round ends music, I wish those were included.
I guess Hidenori Shoji did the soundtrack for this game, he was listed in the credits. This guy does all of the Yakuza soundtracks. Binary Domain is more electronic compared to the rock tracks you hear in the Yakuza games. However the main screen music and main menu music has that Yakuza vibe.
