Greatest song intros evar!!!! - The list to end all lists!

[Is Don on the phone?]

Nirvana- "Smells Like Teen Spirit" Short, simple, and powerfull
GnR- "My Michelle" Sets the mood for the whole song.... In fact, almost every song on Appetite has a good intro.
Weezer- Hash Pipe (does just a hook count?)
Fat Boy Slim - "The Rockafella Skank"
Van Halen - "Everybody Wants Some" (The Mets used to take the field to the intro-so much cooler than the current "Meet the Mets")
