I don't really listen to Wonderland or Dirty Love, either. I got sick of them. I wouldn't say they "aren't good", though!
Love Into the Light really clicks with me. It's cheap/tacky lyrically, but that's the point, really. It's the message that matters.
And I really like the production, honestly. It's so different, for Ke$ha, Greg Kurstin and anyone in Pop music
