As big a week as it was for Drake when "Toosie Slide" gave the superstar his seventh No. 1 on the Billboard Hot 100 (and a record-tying third time debuting on top), the feat may mean even more for the track's producer, Ozan Yildirim.Better known by his nickname OZ (that's "O-Z"), the 28-year-old Swiss beatsmith has assisted household names before -- credits on Travis Scott's 2014 project Days Before Rodeo and Drake's 2016 album Views are among his earliest placements.
