I love you, sincerely (piano ver.)

 is a track in Xenosaga Episode III. It has not been released on any soundtrack or sound selection and not much is known about this track. It is a remix of I love you, sincerely (and, by extension, of title screen) for piano and bass. It is substantially more free melodically than other versions of the theme, even featuring sequences of improvisation (especially from 1:54 onwards).

It plays as the area music in Café Stream on Fifth Jerusalem. It also plays in the following cutscenes:
 * Shion catches up with chaos in Café Stream.
 * Shion enjoys a night out with Allen on Fifth Jerusalem.
