just got this today as well... I heard a lot about it, but had to grab it after hearing Crazy.
By the way, Gnarls Barkley hahah.. awesome name.. anyone know why they chose it? The Bread Truck was my fave Bballer.
The album isn't like Crazy. It's got a lot of different sounds in it, and nothing else that sounds like Crazy.
there are 3 or 4 good Hip Hop/Rap songs.. which are very fresh, another couple of alternative rock songs, Gospel like singing, awesome use of samples and strings. Some of the songs are quite upbeat and dancy, while others are very dark and almost scary.
Hard album to describe, but I can't stop listening to it all day!
