d I didn't notice that.
Also on an unrelated note, I just realised that Ted Bruner, who produced some of Kesha's unreleased songs (Aliens Invading, Frenzy, Lost Weekend, True Love) also produced some songs for Katy (Lost, I Think I'm Ready, several songs sold to Miley/Jessie James) and even Bonnie McKee. So that probably dates those tracks to around 2007-8.
