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

Vaughan Williams' Lark Ascending is indeed beautiful.  Also try his Fantasia on a Theme by Thomas Tallis--the Barbirolli version is my favorite.  And Grainger's Irish tune from County Derry (Danny Boy), in any form but especially orchestral, can always get me.
