Well just listen to what you prefer
Don't let the realism-talibans shy you away from what is the ultimate objective of this -and any- game: Enjoying the experience
I love music from the 80s, but since I share that love with classical, and I like to have more inmersive ambience, I listen to that last one in SH3. Yet some good music from the 80s would be also good to put you in the mood for some aggressive attacks, that's for sure!
