Canadian rapper      
Drake overtakes      
Jay-Z as the rapper with the     most No. 1s in  the history of the Hot R&B/Hip-Hop Songs     chart this week with a jump to  the top as the featured guest on     2 Chainz's "No Lie," bringing the former's  total of leaders to     10.
 
Rap icon Jay-Z pegged his ninth leader with his      
Kanye  West collaboration     "Ni**as In Paris" last November, while Drake tied  HOVA at nine     No. 1s in February when he topped the list -in back-to-back      fashion- with a pair of 
singles  from the smash "Take Care"     album; "Make Me Proud," featuring      
Nicki  Minaj, and "The     Motto," featuring      
Lil Wayne.
 
In an era where featured artist listings are plentiful, it     is no surprise  that Drake has had more leaders (seven) as a     guest act (on tracks by artists  such as Trey Songz, Timbaland,     Nicki Minaj and DJ Khaled) than he has had as  a lead artist.     Other than the aforementioned "Take Care" chart-toppers from     earlier this year, Drake hit No. 1 with his very first charting     single  "Best I Ever Had" in June 2009, on which he was the sole     credited act.
 
Among his nine No. 1s, Jay-Z's has been the lead voice on     four, including  his shared credits on "Ni**as" and "Empire     State of Mind" with Alicia Keys  (2009). Unlike Drake, Jay-Z's     first time in the No. 1 spotlight was earned  with a guest role     on Mariah Carey's "Heartbreaker" in 1999, three years  after his     chart debut with the No. 17-peaking "Ain't No Ni**a," featuring     Foxy Brown.
 
Drake's quick ascension to a double-digit No. 1 tally is     quite  impressive, as it's been just three years, one month and     three weeks since  he claimed his first No. 1 and only five     weeks longer than that since he  first graced the list. By     contrast it took Jay-Z longer (three years, six  months and one     week) just to get his first No. 1 from the time of his  initial     chart appearance while 12 years and one month passed between     his  first and ninth No. 1s.
 
Here is a list of the rappers with the most No. 1s in the     history of  Billboard's R&B/Hip-Hop Songs chart:
 
Drake (10)     
      Jay-Z (9)     
      Lil Wayne (8)

      50 Cent (4)
