First of all, if you're going to cite Roy Buchanan, forget "The Messiah Will Come Again", it's all about this:

The live version #3 from 1974 is better than the video above: http://www.amazon.com/s/qid=1285904782/ref=sr_gnr_fkmr0?ie=UTF8&node=163856011&search-alias=digital-music&field-keywords=buchanan%20hey%20joe
Ditto on anything by Roy Buchanan--an insanely talented individual, but sadly, a terrribly tortured soul. I agree with what someone said earlier about Slash's tone--the day is coming, and its not too far off, where everything he plays will sound the same, much like Carlos Santana.
Here are a few I thought could have made the list (some of these selections are a bit obscure, I'll admit):
Sharp Dressed Man-ZZ Top
Eastbound and down-Jerry Reed
Squealer-AC/DC
I'm Going Home-Ten Years After (Live at Woodstock)
Tattoo'd Lady-Rory Gallagher (Irish Tour '74)
Sign of the Gypsy Queen-April Wine
Limelight-Rush
Terraplane Blues-Foghat
See The Light-Jeff Healey
Snortin' Whiskey & Drinkin' Cocaine-Pat Travers
Five to One-The Doors
Two Minutes to Midnight-Iron Maiden
Do YOu Feel Like We Do-Peter Frampton
Maggot Brain-Funkadelic
The Thrill is Gone-BB King
Miserlou-Dick Dale
Those are just my take on it, but no matter what you think or I think, none of these lists will ever be perfect for anybody, and to be honest, that's what makes them kind of fun.
