I'm a musician myself, and the first music I remember loving (besides The Beatles and Elvis because my mom loved them) was Bach on organ and SW. So you could say that it had a lasting impression on me! (As you all, I'm sure.) Phew, let's see...

1) The whole "Yoda lifting the X-wing" scene
2) Final showdown in Imperial Throne room (chills!)
3) The Flacon in the asteroid belt
4) Obi-Wan explaining the Force to Luke on Tatooine
5) Luke calling to Leia in the Cloud City
6) Rebel fleet preparing for light speed
7) Damn, everything else!

I've been saying for years that the secret behind SW was a mix of storytelling, special effects and music.... thanks for confirming this, people!
