I get what they were trying to do and they didn't really get it. This is what happens when someone who doesn't understand jazz music tries to write a "jazzy song", it relies on a cliche set of chord changes with no proper development which is very fundamental to "real" jazz music. Of course they're trying to imitate the jazz-influenced trip hop of Portishead and whoever, but even as that it comes out below the mark. Great singer though, but she seems lost in this song.
