You don't even listen to her music do you?
"I've been through my sketchy phases, been broke and a ****** waitress,
but I'm not now guess it worked out, got here by running my mouth."
I think you fail to realize that Ke$ha wrote songs since she was 14, some of them even ended up on Animal. She isn't broke anymore, but she was for the few years when she moved to LA alone to pursue her music career. Also, she sent her demos to RCA in 2005, sent from DAS communications (her management) and Luke and Max thought she was a great songwriter and impressed with her demos, so they signed her. No surprise, RCA didn't let her release her debut single till 4 years later and now she's a millionaire but she's still the same girl.
