Katy Perry's first major hit was the song "I Kissed a Girl" back in 2008, and when I heard it I thought, looks like another one hit wonder. Three years later, she's proven she's a multi-hit wonder, becoming the first woman to score five No. 1 songs from one CD on the Billboard Hot 100 chart. Her "Last Friday Night (T.G.I.F.)" set the precedent: It's the latest No. 1 from her platinum album "Teenage Dream." Only Michael Jackson had five No. 1 songs from one album before Perry, from "Bad." But Jackson spent a total of seven weeks at the top with his "Bad" songs; Perry has been at the top perch now for a cumulative 18 weeks!
