Azalea's debut studio album, The New Classic (2014), peaked among the top five of several charts worldwide and received generally mixed reviews. It topped the Billboard Top R&B/Hip-Hop Albums making Azalea the first non-American female rapper to reach the top of the chart. The album was preceded by her debut single "Work", and generated the US Billboard Hot 100 chart-topping single "Fancy". Azalea was featured on Ariana Grande's single "Problem", which peaked at No. 2 while "Fancy" was No. 1. Azalea joined The Beatles as the only acts to rank at numbers one and two simultaneously with their first two Hot 100 entries. She achieved three top-ten hits simultaneously on the Hot 100 with the aforementioned songs along with the album's fifth single, "Black Widow", later that year.
