Have you ever heard a song and been so moved or so inspired that you cry? If you haven't I recommend the following:
Sigur Ros: Glosoli
Flaming Lips: Do you Realize
KD Lang OR Jeff Buckley: Hallelujah
Ludwig van Beethoven: Moonlight Sonata
And just to get you started, here is Glosoli. I once gave a presentation on this video and how it reflectd modern art ideals. It was for my 20th Century Art History class.
