Rush and Keep Alive share chorus parts.

Diapason, Zero, Galm 2 have similar base tunes, along with many other ACZ OSTs.

It seems like Ace Combat themes (5,0,6, AH and AHL especially) seem to have theme melodies that a portion of the OSTs always include.

And of course, Stonehenge and Stonehenge's Attack. Internal remixes don't count because they are from the same soundtrack.
