Okay, I'm not a GR HATER by any means, and I have no problem with GoP, BotH, HoW or IY, but here's why I don't like the rest:
1) BTM: beginning: cheesy and repetitive. middle: way too many simple two chord vamps. keyboard/guitar duo in unison sounds cool but is ultimately pointless. ending: mindless indulgence that's supposed to be experimental but ends up sounding like a less talented Mars Volta.
2)At: horribly dull. The mood is mildly cool, but couldn't the song have gone somewhere?
3)Hf: All the shades of Opeth with none of the soul. Opening couple of minutes sound way too trendy, first death riff sounds like a recycled Still Life bit... acoustic parts actually aren't too bad but still are only a pale reflection of their better mellow moments... heavier sections that follow are too repetitive, and the last couple of minutes are mildly interesting but only serve to further bloat an already ridiculuously bloated monstrosity.
4)TGC: The main riff is just repeated too many damn times, both at the beginning and end. The syncopated chugga chug riff is okay but many other bands do this sort of thing much better. I do like the middle when it starts to develop a little bit, but these parts are ruined by the monotony that bookends them.
Having said all that, the rest of the songs kick ass!
