Greatest Intro songs!!!

  Alright sports fans, there is not much that gets a
fan more pumped up than a great intro or at bat song.
As a Jazz fan, I get so pumped up when I am at a game and they are doing their intro!  I guess its my "kid in a candy store" moment.  I just get giddy.  Wish I could have had the opportunity to do that just once in my life.  I guess I will just have to live vicariously through the pros....So the question I have is, what are the best intro or at bat songs?  I am a big fan of just about anything AC/DC, specifically Thunderstruck.  I also like Johnny Cash, Gods gonna cut you down.  So what do you guys think?  Post songs in comments and I will compile a list and do an update to this post with the top picks!
