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

There are many, but these are some that stand out: Just about everything on MFSL's 1972 Original Master Recording of Neil Diamond's "Hot August Night" Live at the Greek; Van Morrison's "Avalon Sunset" especially the last track "These are the Days"; everything of Eva Cassidy, especially "Songbird".

Joni Mitchell - Blue hotel room
Jonas Stark Bach - Suites for Solo Cello; Sonatas in G & D Major the Philips Mercury Living Presence recordings. It sounds holographic and hypnothic you hear Jonas working.to get it this intimate.

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.
