I have more than 50 movie soundtracks on CD. And I'm supposed to choose a "best" one? Riiiiiiiight.
Okay, I'm going to go with the soundtrack for my favorite movie, The Man from Snowy River. It's composed by Bruce Rowland, and I absolutely love it. In fact, it was playing in the background with both Dano and Mercy were born. I find it soothing, exciting, restful, and stimulating. I know every song intimately, and I've been able to play the main theme on the piano from memory since I was 11 or 12. Beautiful, beautiful music.
