Bruno Mars’s “24K Magic” blasts onto the Hot 100 at #5. It’s the highest-debuting hit of Mars’s hit-studded career. Only three other singles have debuted in the top five so far this year. Zayn’s “Pillowtalk” and Justin Timberlake’s “Can’t Stop the Feeling!” both opened at #1. Major Lazer’s “Cold Water” (featuring Justin Bieber and MØ) bowed at #2.
