[Raizinman]

I heard it through the grape vine.

This has a really neat intro. Make sure to turn up the volume as you need it loud to hear all the instruments.

 

[classy]

Metallica Enter Sandman
Schooly D PSK

Two of the best, "INTROS", of all time. Turn it up real loud okay;

I can be in the WORST mood but if the radio is on and I hear AC/DC's "You shook me all night long" start up I immediately start the air guitar and begin jumping around. Funny, because in general I don't really care for AC/DC - but that intro is killer.

 

[KGB]

Pink Floyd "Shine on You Crazy Diamond".

 

[Sheik Yerbouti]

Voodoo Chile (slight return) - Hendrix or SRV
Texas Flood - SRV

 

[SP33Demon]

I'm kinda digging THA's new classical inspired intro for 2011:

[Pheran]

Lots of good suggestions here already. This isn't a song that most people will know, but I absolutely love the intro to Lift Me Up by Yes, the first minute is just awesome.

 

[vi edit]

Love the bass line to "Hey man, nice shot" by Filter.

 

[BurnItDwn]

Bloodbath - The Soul Collector

 

[Squisher]
