Gradius one music from NES
Start a new mission on stage 1 of Gradius Galaxies. Somewhere in the stage, there are 2 strips of horizontal rocks (one longer than the other). Carefully travel through the small gap in between the 2 rocks and you'll get 5000 extra points. Complete the game as normal and when you return to stage 1 again on the next loop, the stage music will change to Gradius one from NES.
