Wow, this thread goes back a ways. Here's a few that come to mind for me:
*Pick any song off Eat a Peach album, Allman Bros.
*Red House-Jimi-"that's allright...I still got my guitar, look out baby!"...sweeeet
*Hotel California-Eagles-even non-players whistle and air guitar this one, a sure sign
*Crossfire-SRV-melodically and technically, one of his best
*Sultans of Swing-Dire Straits-he really might know "all the chords" :)

Ok, that's 5, but I gotta mention (even though it has been) Stranglehold-Ted Nugent...think it's his only song I like though.
