Billboard's Hot 100 chart turned 50 this week and what more appropriate way for it to celebrate than with more charts. The first of a series of charts leading to a special edition next month is online today, chronicling the artists who have had the most No. 1's on the chart in the past five decades.
The surprises aren't No. 1 The Beatles, with 20, or No. 2 Mariah Carey, with 18, but farther down the line. The Bee Gees come in at No. 9, with nine chart-toppers, ahead of The Rolling Stones with eight. And The Stones are tied at No. 12 with Usher, who apparently rehired his mother as his manager yesterday, firing manager Benny Medina and his publicists because of the disappointing showing of his album "Here I Stand." (Yeah, it couldn't be because the album wasn't, you know, um, good.)
And speaking of not good, Katy Perry's "I Kissed a Girl" remains at the top of this week's Hot 100, for the seventh week. Watch out, Beatles.
