Okay, how about:
-- Dream Theater -- As I Am and This Dying Soul off of "Train of Thought" (if you're into a sort of metal/prog rock sound).
-- Bloodline -- Calling Me Back.
-- Gov't Mule -- Perfect Shelter off of Deja Voodoo, Brand New Angel and Child of the Earth off of High & Mighty, Worried Down With the Blues and Beautifully Broken off of The Deep End (Volume 1).
-- Jim Suhler & Monkey Beat -- Bad News and Graveyard Train off of Shake.
--Jimmy Thackery -- Detroit Iron.
--Michael Katon -- Boogified
--Miles Davis -- Ah-Leu-Cha off of Round About Midnight.
--Philip Sayce -- Powerful Thing and Blood On Your Hands off of Peace Machine.
--Robben Ford -- Moonchild Blues (from Truth), Rugged Road (from Handful of Blues), and Worried Life Blues (off of Mystic Mile).
--Wynton Marsalis -- The Party's Over and Glad To Be Unhappy (from Std Time Volume 5: The Midnight Blues).
-- Back Door Slam -- Heavy On My Mind and Stay off of Roll Away.
Sorry, but once I started I couldn't stop. Edited to add, these aren't exactly "pretty" songs, but ones that I like that several are a bit obscure.
