ok, the list is about half right in my opinion. The first thing that struck me was the shameless lack of metal songs. Come on, you have Green Day and Smashing Pumpkins but no Metallica, Motorhead or Slayer? Whats up with that? You could do a top 20 list on those three alone.
Here's a few:
Slayer- Raining Blood
Metallica- Master of Puppets
Van Halen- Unchained(now thats a cool riff)
Black Sabbath- Black Sabbath(the darkest riff ever written and root to all metal. I swear that riff envokes the devil himself. Iron Mans cool but...)
AC/DC- I think Highway to Hell is a beter riff
Motorhead- Ace of Spades(bass riff)
Judas Priest- Electric Eye
Rush-YYZ or Limelight
Ted Nugent- Cat Scratch Fever of Stranglehold
Boston-Piece of Mind
Doobie Brothers- China Groove
Kanasas- Carry On....
I also agree with the Cream and Jethro Tull additions as well as Dire Straits, Deep Purple(though Highway Star is better), GnR, Layla, RATM, Skynard, Stones and Zep(and a dozen other Zep songs) from the original list. But I feel Stairway To Heaven is a tired worn out, overrated, boring song. GASP! There I said it, now let the angry posts begin!

Yea and hang the sick pervert that molested this child by them.

I think law enforcement should be looking into why this young boy has such a fixation with sex and and sexual organs. I'm no expert but this clip smacks of a history of sexual abuse. It's very disturbing and I hope that someone who can do something about it sees it. It's not cute or funny.
