Love Like A Sunet, Pt. 1 - Phoenix
Untitled - Neutral Milk Hotel
Exit Music (For a Film) - Radiohead
Hoppipolla - Sigur Ros
Digital Love - Daft Punk (this just brought a huge smile to my face)
Do You Realize?? - The Flaming Lips

I've gotten chills from all these songs at full blast. It's the most epic feeling.
