The soundtrack sports 21 tracks, which as far as I can tell covers the music from the entire game, plus what seems to be a remix at the end. (I was not provided with a track list, so I cannot be absolutely certain on this.) The tracks range from pretty raw techno to more melodic pieces, including the obligatory vocal end-game track -- in the original Japanese, no less.
Something that was quite prevalent in the music of The Bouncer, which I really only noticed when I listened to the soundtrack outside of the game, was the heavy use of classical instruments. Indeed, more than one piece uses these more traditional instruments almost to the exclusion of anything else. The haunting Track 18 is a case in point, and one of the best pieces on the soundtrack, with its point-counterpoint pianos and violins.
There is quite a bit of good stuff here, even if you want to skip the sentimental ending theme, and there are at least one or two tunes of a variety that will please you. There's some serious music, some pounding music, and some atmospheric music. The soundtrack is definitely heavy in the electronic section, with lots of synth and electric guitar, so be forewarned if those aren't to your liking. Those who are fond of electronica, with the more than occasional foray into traditional music, will probably be pleasantly surprised by the music on The Bouncer's soundtrack.
