It's absolutely amazing how people still don't get the concept of a scores soundtrack, then rate it low because "It's just boring background music." If you scroll down to the track listings and you don't see any artists listed, that should be your first clue. With that said...
I think Hans Zimmer did an excellent job on the score for the "Holiday," and it's very obvious that he took his inspiration from the wonderful Ennio Morricone, a legendary composer whose music is actually featured in this movie (when Jack Black's character, Miles, meets Kate Winslet's, Iris, for the first time, you can hear it playing from his car). I'm a sucker for lushly romantic music, and if you are too, you won't be disappointed in this music.
The only reason I gave it 4 stars instead of 5 is because the music is somewhat repetitive. There are three or four main themes that Zimmer has interwoven and enhanced. It also does not include, to my knowledge, the songs that were written for the characters of Iris and Arthur. Here are a few of my favorites:
"Maestro" - This is the opening theme at the very beginning of the movie, played by Miles on the piano. It's absolutely beautiful and one of the more Morricone-esque songs on the score.
"Iris and Jasper" - This song plays throughout the scene at the office, when Iris learns of Jasper's engagement and goes home alone. It's mostly piano and strings, and there is gorgeous guitar at the end.
"Anything Can Happen" - Mostly piano, this has the Santa Ana winds theme when Iris is standing outside her LA house after meeting Miles.
"Kiss Goodbye" - This is a reprise of the Maestro theme and has a little bit of the Santa Ana winds theme as well, but it is much more upbeat than in 'Anything Can Happen' and has some choral voices.
"Cry" - Most everyone who liked the score has been looking for this song -it's the upbeat energetic song playing when Amanda is running over the snowy countryside to Graham near the end of the movie.
Please definitely give this soundtrack a try if you're into movie scores. Hans Zimmer really did a wonderful job, and it's a great CD to relax to.
