Tron definitely deserves to be listed. When I went with friends to see it the first time, we had heard mixed reviews. We decided that a huge part would be if people appreciated the musical component of that film.
On its own, the music from Hanna is pretty good. When I consider stuff like a film score, I always connect the way it was incorporated into the movie as well, which is why I list Hanna here. Some aspects of it flowed together like a music video and both the visual and musical aspects complimented each other really well in that movie.
I know anime isn't everyone's thing, but Cowboy Bebop was simply amazing in many regards. The music is no exception. I still regularly listen to the soundtracks to that and it's easily been 10+ years since I originally saw the series. The way it gets tied to the series has always impressed me. I've seen it quite a few times by this point, but I could name the scene that most of the songs were used in if I heard them after my first or second watch. Yoko Kanno did amazing things with that series.
