Ke$ha is a new artist who rose to the top of the charts last year with her smash hit "Tik Tok". It is the first #1 single of the new decade...and nobody else will be able to do that. Her debut album dropped January 5th, and she's expected to beat Susan Boyle for the number one spot with over 110,000 copies in her first week which is great for a new artist. Will you be buying? Peep her performance of Tik Tok below!
