Kesha Sebert AKA Ke$ha. She has made it big this year starting off the 2010 new year breaking records for digital sales with the lead single off her debut album. Her song, "Tik Tok" sold 610,000 digital tracks in one week! That was the new record for a female artist, passing Lady Gaga's "Just Dance." As far as overall digital sales, it was directly behind Flo Rida's song, "Right Round" which she happened to sing on also! She is known for singing about drinking and partying and her overuse of auto-tune. The dollar sign in her name was supposed to be ironic. In an interview, she said she heard herself on the Flo Rida song on the radio at a grocery store while buying canned soup with food stamps. So the dollar sign was there before she actually really made money.
