What sends shivers down your spine when you play it on your system?

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.
