Britney Spears' "Till The World Ends" may not be our pick for Song of the Summer, but it's proved itself to be invincible on the Hot 100 charts—even after the false prediction of Judgment Day came and went—currently sitting at No. 9 after 14 weeks. Considering it's largely responsible for facilitating yet another Spears "comeback," why would anyone, let alone a pop singer-songwriter, want to give such a goldmine away? Ke$ha, the song's author, has no regrets regarding passing the super catchy dance track onto Brit. Impressively, she has her ego in check, and is all kinds of generous for a 24-year-old. "I’ve never been more proud of anything in my career," she told Vulture Tuesday night. At least she got to lend her voice to the song's remix. But did that give her a case of songwriter's remorse? Apparently not:

"It really solidifies me as a songwriter in the pop music world, which is what I consider myself first and foremost. So it actually is really, really exciting for me when I hear [Britney] sing it. Like, when I hear my own songs on the radio I have to kind of turn it down or change the radio or whatever. When I hear that, I fucking blow the speakers out and I order everybody to dance."

So do we. But maybe Ke$ha should start saving a few of her better tracks for herself? If only to avoid being engulfed in another Real Housewives-related controversy. That won't do anything to help her rep, and no one wants to hear their name in the same sentence as Simon van Kempen. Then again, aligning yourself with musicians of the Real Housewives is definitely a way to ensure you won't have to listen to yourself on the radio.
