As of this week, T.I. is the king of the Billboard Hot 100.  “Live Your Life” (with Rihanna) spends a fourth non-consecutive week at #1 with a bullet…which means that he has spent more weeks at #1 than any other artist in 2008 (”Life,” combined with his other #1, “Whatever You Like,” makes 11 weeks at #1, beating Flo Rida featuring T-Pain’s 10-week stay with their song “Low.”)  I’m predicting one more week for “Life” though next week, because last week’s threats, Kanye West’s “Heartless” and Katy Perry’s “Hot N Cold,” both dropped positions.  “Hot N Cold” slipped one position to #4 (but retains its bullet), while “Heartless” drops from #4 to #12 and loses its bullet.  The only threat this week is Beyoncé Knowles’ “If I Were a Boy,” which rises two spots to #3 with a bullet and is the Sales Gainer of the week.  This is possibly because of her performance of the song on MTV’s “Total Finale Live” special last week, which included her other single, “Single Ladies (Put a Ring on It),” which is ironically the Airplay Gainer of the week (it rises from #39 to #28 this week.)
