Song Intensity

[J Peterson <Presence@xxxxxxxxx>]

What about song "intensity?"  I'm talking about sitting in a 
completely
dark room, music on at a good volume, equalizer in the V formation; 
and
the song just gets in your head and MOVES you.  You come out of the
experience thinking "holy sh*t that was heavy."  Here's some of my top
faves, and since Zep is one of them this post has partial Zep content 
:)

Led Zeppelin - Dazed and Confused
Procol Harum - Simple Sister
Manfred Mann's Earth Band - Waiter, There's A Yawn In My Ear
Jimi Hendrix - Voodoo Child (Slight Return)
Metallica - Blitzkrieg
