I am voting a 9 and here's why:
1) I really like this album. My favorite tunes at this moment are "Shadow People", "U Get Me High", "all You Can Carry", "Red River", "American Dream Plan B", and "Power Drunk". The other tunes are pretty good as well. It's unusual for me to like a new release this much, and have so many songs that I really like. In the old days, you'd buy an LP and play it to death, usually one side more than the other, and you'd get to know that whole side and the songs would get burned in your brain, even the ones you didn't like at first. In today's day and age of the 'Track Forward' button which can be pressed the instant you decided you don't like a song, getting the whole album in is unusual.
Still, I find I am playing this all the way through a lot, both at home and in the car. The fact that it is not heavily compressed (unlike the downloaded stereo files) makes it even better. You can crank this thing up and there are tunes that really shine when played loud.
Now the mix, well, as I said earlier, it's not an amazing surround mix like the Bob Marley disc, or a SW mix. At times you have to remind yourself that it's a 5.1 mix, but it works. It's there, it's surround, but it's just not extreme.
So, I feel this is a 9. Great disc, great material, good surround mix.
Your results may vary.
