Katy Perry’s most recent journey to the top of the Billboard Hot 100 has put her side by side with the King of Pop.  “Last Friday Night (T.G.I.F.)” comes in at number one this week, marking the fifth chart-topper from her “Teenage Dream” album.  She’s now the first woman and only the second artist to achieve the feat since Michael Jackson.  Perry’s “California Gurls” topped the chart last June.  It was followed by Perry’s “Teenage Dream,” “Firework,” “E.T.” and now “Friday.”  It took her a little more than 14 weeks while Jackson did it in nine-and-a-half months with his 1987 album “Bad.”  However, during the run Perry has spent a total of 18 weeks at number one while Jackson only held the top spot for seven total weeks.

As for the rest of the Hot 100, last week’s number one — LMFAO’s “Party Rock Anthem” — slips to number two.  Meanwhile, Maroon 5 jumps five spots to number three with their Christina Aguilera collaboration “Moves Like Jagger.”
