Another vote for "The Lark Ascending", that is what I thought of when I read the post. It's rural England in late spring, set to music.
Other Classical offerings: Albinoni's "Adagio"
Richard Strauss's "Metamorphosen"
That is his response to the end of World War 2 and I believe, finding out about the Nazi Camps.
For non classical: Sara K, "Water Falls"
Mark Murphy, "Love is what it Says"
The last two are both beautiful music and the best quality recordings I think I have.
