I wish I had time to read everyone's replies, but don't, so I'll just reply to the OP.
No, you're not the only one...
With the 3 albums that preceded this one, I fell in love at first listen. I don't necessarily think that's a great thing, because I don't listen to them at all anymore; it seems the ones that I need to listen to time and time again are the ones that stay with me forever.
That being said, I think this album is very different for them. Very different. It's obviously a strong album because I didn't find myself wanting to click the next track button on the cd player. I think it's one of those albums like SFAM or even TOT that will take a little while. I'm working 11 hour days and have a house and kid to take care of, so I've only gotten through the disc once. I plan on listening to it one more time and then putting it away for a few days and then getting it back out. I don't know why, but with the albums that I mentioned, along with 6DOIT, when I do that I'm able to get the most out the music.
So, I'm not going to try to pick a favorite song at this point, or make too many comments about the album. I will, however, say that although I'm sort of against the sections with the electronic drums, they do seem to work somehow. But there are so many new things on this album that it's going to take me a while, though I'm getting the feeling that when it does fully open up for me it will be a monster. One other comment I have, though, is I'm thinking that MP was the driving force for the heaviness, because for the most part, I think it disappeared.
That's my thought for now. All you can do is relax and listen to it for what it is, and hopefully it will find its way into your head and heart.
