It mines the same formula they've been using for years now, which isn't necessarily a bad thing, because they do is extremely well. And yeah, she's a helluva singer. Too bad she can't seem to write a really good set of lyrics-- if she could, this band would be dangerous.
I like the fact that they went from purely an R&B duo to a full rock/soul band.
I do agree with you on the lyrics, but yeah she is one of the better singers out there.
