There were more than 280 different songs nominated, a testament to the breadth and depth of the genre, and how the term ‘greatest’ can be interpreted in various ways.
Each critic voted for five songs, ranking them from one (favourite) to five (5th favourite). We approached hundreds of hip-hop and music experts – critics, industry figures, artists, academics – and 108 from 15 countries across six continents responded by filling in an online poll in August and September 2019.
