Listened to MoB this morning with really really crappy audio, and thought then that it was a really dull track. But I thought that was unfair and waited until I got home so that I could hear it with "proper" sound.
I actually think this track is alright. I like the main melody, the one in the beginning. The chorus is nice. I disagree with those saying that the instrumental section feels forced. I actually think it fits rather well both from a song-structural perspective and a thematic perspective, given what's going on in the lyrics. And the JM soloing was great, that was really fun to hear. I only wish that Petrucci would have held back for once and let Myung handle it by himself. The pre-choruses were also quite nice, and blended some cool melodies with decent silly lyrics.
As to things I didn't like. The first verse is a bit boring, and the second verse is an absolute mess in every way. And the Metallica-ish bad-ass riff in the beginning did nothing for me and struck me as a bit lazy. And I absolutely agree with someone a while back who said that JLB is over produced.
Other than that, I liked this one. I didn't love it, but it was fine.
I'm not sure if I'd call myself a casual fan, but I guess since I'm not a drummer I never thought MP's fills were repetitive. As long as they work in the context of the song, it's fine by me.
I am both a non-casual fan and a drummer, or at least used to be, and even I have never noticed this whole repetitive fill thing.
