Play that funky music, white girl

Sweet Child o' Mine was on the radio last night, and it got me thinking about the best guitar riffs ever. 

My (somewhat sheltered and probably very limited) list:

• Sweet Child o' Mine - Guns N Roses
• Around the Bend - CCR
• Let's Hang On - Four Seasons
• You Shook Me All Night Long - AC/DC
• Anything by Jimi Hendrix (but I prefer the Star Spangled Banner)
• Beat It - Michael Jackson/Eddie Van Halen
• (I Can't Get No) Satisfaction - Rolling Stones
• Black or White - Michael Jackson/Slash

What am I missing? This could be one helluva mega-mix. Just saying.
