Weekly Survey: What’s the best album opener of all time?

Weekly Survey: What’s the best album opener of all time?
Before an album comes out, there is much agonizing over what order the songs should be placed. Some great examples:

Nirvana, Nevermind: “Smells Like Teen Spirit”
U2, “Where the Streets Have No Name”
The Clash, London Calling: “London Calling”
Led Zeppelin IV: “Black Dog”
Oasis, Definitely Maybe: “Rock’n’Roll Star”
Guns ‘N Roses, Appetite for Destruction: “Welcome to the Jungle”

What’s your pick for the best-ever side one/track one? Let me know and we’ll fight about it on my 102.1 the Edge show at 6 pm tomorrow. Of utmost importance is track one. Whatever is chosen has to grab the listener right away and make a STATEMENT that will reverberate for the rest of the record. How should the experience of listening to this album begin?
