Call me a geek but 'Sheep Go to Heaven (Goats Go to Hell)' by Cake.
I absolutely love Henryk Górecki's Symphony No. 3.
I don't know what it says but it makes me want to go do something great.
Oh and King Kong's entire Funny Farm Albumn

The Grateful Dead must have covered the whole gamut of western music.
I'm rummaging around for Blind Willie Johnson geek. That song is ethereal
I kinda did that with Hurt by Cash....but only because he was dying at the time. The solo from No More Tears, (A work by Zakk Wylde) always amazes me.
