Stylus Magazine, who were mostly mixed to negative for Young's previous number ones, rated "Leave Right Now" with 9/10, saying "Better. Much, much better. By this time Will was comfortable as a popstar, prepared to add a little WTF to his videos (here he has a fight with the viewer in an art gallery), and had his style down pat: jacket and jeans rocked to a level not seen since Lovejoy and Tinker were bossing things in the late 80s. He had songs to match as well: 'Leave Right Now' is just one of the most English songs ever, which is understandable: what could be more English than a privately educated homosexual? The guy's a moderate genius—Dido with testicles and a heart."^[2] In 2007, Freaky Trigger ranked the song at number 54 in their list of the "Top 100 Songs of All Time," with critic Pete Baran calling it "one of the ballsiest songs of the noughties."^[3] In 2020, The Guardian ranked "Leave Right Now" at number 74 in its list of "The 100 greatest UK No 1 singles".^[4]
