It's not heavy metal, but hard rock. I believe the singer is singing the song in first person, like narrating whats happening. I think hes like walking around and notices a guy staring at him and then the chorus kicks in and I'm pretty sure it's about him fighting the guy. Pretty mainstream song, kicking myself now for forgetting it. Chorus was super catchy, and the tempo definitely picks up during the chorus. Dammit...what is it!!??
