IMO most of these intros suck with the exceptions of:-
Ghost in the shell (both series) - great intro to a great series.
Elfen Lied - The series didn't deserve such a great intro.
Ergo Proxy
Here are some additions
Harlock Saga - one of the best ever
One of the least conventional from Requiem from the Darkness.
Record of lodoss tv. The series wasn't as good as the OVA but good intro.
I had to put in one of my favourites Desert Punk.

Did anyone mention the new guyver? Here it is http://www.youtube.com/watch?v=7gLwBN1sSQs The vocals are pretty poor until about the end but the intro starts great. As far endings go, it's hard to top Black Lagoon or Wolf's Rain.

The Dragon Ball GT Opening kicks all kinds of ass, even though the show was a low point in the Dragon Ball series.
Dragon Ball's opening theme was fecking tight too.
Yu Yu Hakusho is at the top of the list also.
Trigun too
