It's been 30 years since I started actively listening to film scores, not just with the film, but away from the film as well. People often ask me what my favorites are, and I finally decided to make an official list. I'm careful to note that the title of this list is "favorite 100" not "top 100". These are not all critically-acclaimed, nor are they selected primarily for how well they work in the film (although that is a consideration).
The criteria for me is in this order, (1) Instrumental Underscore only, no song soundtracks, (2) musical excellence, (3) Effectiveness in the film. (4) Originality (though not without the excellence. There are plenty of scores that I consider highly original, but not musically excellent.
To prepare for this list, I listened to well over 400 soundtrack albums this year. Most were titles I hadn't gotten to, but some were refreshers. So I feel very confident in my opinions on this list. Also, please know that I think EVERY score here is GREAT! #100 doesn't mean "sucks". #100 is an excellent score! I just happen to like 99 (out of how many hundreds of thousand possibilities?) more. Two things to note: First, there are a lot scores from the 3 J's (John Williams, Jerry Goldsmith, James Horner), but a lot of total composers represented. Second, there is an obvious lack of diversity. I wish that weren't the case. I tried my best to judge the music only, and did not want to include any composers for reasons other than how I honestly felt about the work itself.
