I love Thundarstruck, and it obviously plays well with our mascot, but I'm only one opinion and in life we sometimes need to change.

How long is the ideal intro song? There are many great songs with powerful beginnings. Sticking with ACDC, "Are you ready" has an awesome intro but loses steam before the one minute mark. So I presume something with a longer run would be desirable?
