Not sure how much truth there is to this but I just saw on YouTube (of all places) from someone that reported about the leaked announcement of Kesha's single coming in August and her separating with Kemosabe that apparently the single was supposed to come out then but was delayed (for unknown reasons) by RCA.
As I said, not sure how much truth there is in that though. Could just be more B.S. to make her label look bad because the rumour wasn't true. But it does seem weird that they'd update her website and then do nothing.
