Song With Best Beginning

I don't know if these are the best but off the top of my head here are some favorite songs where I really love the intros.

Guns N Roses: You Could Be Mine
Metallica: Disposable Heroes
Rolling Stones: Paint It Black
Slipknot: Surfacing

and

Blind Guardian: Sacred Worlds

Warning you will feel epic after the first 2 mins of this song.

Yes I woke up very angry this morning.

I'll nominate "Cortez the Killer" by Neil Young and "Can You Hear Me Knocking" by The Rolling Stones.

Reelin' in the Years, Steely Dan. Won't Get Fooled Again and Baba O'Reilly, The Who. Brown Sugar, Rolling Stones.

It has to be the first notes!

Shine on your Crazy Diamond
Time
Locomotive Breath
Pigs

Malcolm McLaren's "Tracing Back My Steps In Time" from album "Paris".

For me it's Van Halen "Dirty Movies" off of Fair Warning.
