For Godsmack I'm going to go with "I Stand Alone" I always use it to get myself pumped up before I go running. It's just a overall very adrenaline fueled song. Sully's vocals are complete badass in the song, The lyrics are about as badass as you can get, the drums are loud and powerfull, and the intro is by far one of the best intros ever. All that adds up to be one kick ass song.
