Those songs – “Fancy,” and Ariana Grande’s “Problem,” featuring Azalea — were the first of six top 40 hits for the rapper, who later scored with tracks like “Black Widow” and “Beg for It.” When Azalea’s debut album The New Classic debuted on the Billboard 200 chart, it was the highest-charting rap album by a woman in nearly three years. This year, Iggy is a finalist in 11 categories with 12 entries, competing against herself for Top Rap Song for her hits “Fancy” featuring Charli XCX and “Black Widow” featuring Rita Ora.
