Something else I really enjoy about the song I just found out is listening to the guitar when it does the chords it does from :50-1:15. Its played later in the song also, but you get the idea. Anyways go full blast through some headphones for this part and you can feel the soundwaves from Jimmy's guitar slamming into your right ear, pulled through your head, and being sucked back out through your left ear. Pretty cool.
Anyways I guess thats the main point, there are so many parts and levels to the song, everytime you listen to it, you catch something small, new, and great, and its all compiled together to make an awesome song.
