Huh. I wasn't expecting this album to sound like this at all. I liked it, I dig her style, and while there are one or two songs I most definitely did not like, I thought it was a solid effort overall. I didn't love it nowhere near as much as you did though. I didn't like "Mowgli's Road", thought it felt completely misplaced and was a real letdown after the first four tracks (all of which were so strong, "Shampain" being the standout for me). I believe "The Outsider" was the other one I disliked.
I agree about "Guilty", the lyrics are very cheesy, but the vibe more than makes up for it. "Oh No!" has what might be the catchiest and most memorable hook in the album, and "Numb" just rounds the whole thing off perfectly.
Overall, I think the album might grow on me with future listens. I'm impressed, I'd be lying if I said otherwise, but it didn't quite grab me on first listen.
Now, I'm excited for Electra Heart. From what I've seen, it's a concept album and a near 180 shift from the sound that's found in The Family Jewels. It appears to be more electropop and dance-pop oriented, which is more my thing.
