Serena Williams sat down this weekend to DJ a one-off show on Beats 1 titled "Champ." Williams led off her hour-long set with Alicia Keys' "In Common" and two Irene Cara songs she uses to get in the zone on the tennis court. Her pop-heavy playlist — Taylor Swift, Rihanna, Adele, Justin Bieber, Katy Perry, and Miley Cyrus — also included songs from grime superstar Skepta and the Disney musicals Frozen and The Little Mermaid. Naturally, Williams slipped in her friend Beyoncé's "Single Ladies," too. The show will re-air on Beats 1 at 9 p.m. PT (6 p.m. ET) on Sunday, September 11, but you can stream the songs on Williams' playlist via Apple Music below.
