#1 Guns n' Roses "Sweet Child O Mine"
(Not my kind of song at all, and even Slash hated it. Still, it rules.)

#2 Deep Purple "Smoke On The Water"
(I'm jamming to it right now, and it is just too sweet.)

#3 Jimi Hendrix "Voodoo Chile"
(Hendrix rules.)

#4 Metallica "Enter Sandman"
(I'm not big on the song, but the riff is good.)

#5 Jimi Hendrix "Purple Haze"
(What'd I say? He rules.)

Honorable Mention:
Guns n Roses "Paradise City"
White Stripes "Seven Nation Army"
Pantera "Cemetary Gates"
