I don't particularly listen to anything dependent on the outside elements, however one score that makes me think of rain is Michael Nyman's 'The End of the Affair'. That's most likely as it seems to rain constantly in that fine film, I guess.
I just finished listening (twice in a row) to the recent LLL release of Danny Elfman's "restless," and it would be the perfect accompaniment to a light spring rain, with the sun peeking in and out of the clouds.
My go to is Williams' Tree Song CD which also includes his Violin Concerto and Three Pieces from Schindler's List. Totally rainy experience.
To the guy who said Witches of eastwick, it's not subliminal, it's because that whole openin montage it's pouring rain and stormy.
In that case maybe I "subliminally" remember the beginning of the film? I saw it once when it was released, didn't like it, forgot it.
On the other hand I bought the album weeks before I saw the film and fell in love with it, playing it over and over. As I live in the UK it's not a stretch that my "rainy opinion" was formed before seeing the film.
Still, you could be right!? 26 years is now a long ago memory
When it's raining outside, what do you find yourself listening to? Or does the weather ever play a role in what you listen to?
For me, it always seems to be raining whenever I listen to James Horner's Titanic (the "Rose" cue is perfect for watching the rain fall).
I always choose a tune that makes extensive use of piano, or even a solo piano cue. "Neverland: Piano Variation In Blue" from Finding Neverland (2004) in particular always works for me on days like that.
There is also something about 0:57-1:45 of "Professor Alexander Hartdegen" from Time Machine (2002) that always reminds me of rainy days.
I find the melancholy tunes of Thomas Newman go hand in hand with the falling of rain. Sitting in the gathering dark, rain hitting the rooftops and windows and the sounds of his heart-tugging musical sequences from things like FINDING NEMO, LEMONY SNICKETT or ROAD TO PERDITION really stir my emotions.
