A 30-second snippet of the new Britney Spears single "Till the World Ends" was released on a German Amazon site.
Ke$ha wrote the song and spoke about it with Spin:" That song is me imagining her and any female musician touring the world. You know, when you got out, and you're having an amazing, magical night and you don't want to go to sleep and you want it to last until the world ends."
Listen, AFTER THE JUMP…
