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

“The Ecstasy of Gold” orchestral intro on Metallica’s “S&M” CD. 
Chrissie Hynde singing "There's a Thin Line Between Love and Hate" on the Pretenders Learning to Crawl LP. Gets me every time. Check it out.

John Coltrane's "A Love Supreme"

Aretha Franklin's heartfelt "Angel" written by her sister, off the Hey, Hey (The Other Side of the Sky) album. Of all Aretha's great albums,  this one song off one of later lesser records is so personal it always grabs me.

The Who; “Who’s Next”

David Bowie; “The Rise & Fall of Ziggy Stardust and the Spiders from Mars”

Bachman Turner Overdrive; “Not Fragile”
i know the Iona Brown with Sir Neville Marriner (the “first” one) recording of “The Lark Ascending” on Argo the best. Maybe it was love at first sight, but that’s a great performance. I like the “Fantasia on a Theme By Thomas Tallis”, same recoding, even better. 
Arvo Part: “Tabula Rasa: I. Ludus”. There is a portion towards the end where there is a cacophony of bells that sound like Shinto temple bells or something. I love the whole piece, but that is a very holy crap  moment.
