NOW 77, the U.S. series' first installment for 2021, arrived in January, collecting some of the biggest hits from the waning months of 2020. Chart-topping hits "Mood" by 24kGoldn featuring iann dior and "Positions" by Ariana Grande are joined by other notable pop radio fare such as Billie Eilish's "Therefore I Am," Sam Smith's "Diamonds," BlackPink and Selena Gomez's "Ice Cream," and Dua Lipa's "Levitating" remix with DaBaby. Late rappers Pop Smoke and Juice WRLD are also honored with posthumous track inclusions. While not as exciting as some previous collections, it captures this particular moment on the pop landscape. ~ Neil Z. Yeung
