Shared Music pieces between films

I've just finished watching Predator 2, and in the scene where the
character, Danny, is investigating the penthouse, the piece of music in
the background is the same as a piece used in either Alien, or Aliens (in
the quieter sections of either films - I'm unsure which). Looking at the
credits of Predator 2 there is no mention of a classical piece and I
wondered if anyone could help. I also think the same piece has been
used in other films.
