The Weeknd’s embattled HBO series The Idol finally premieres in June and looks to prove the doubters wrong, the superstar has preceded the fictional music-industry drama with a new single that should heat up the charts in real life: “Double Fantasy” reunites The Weeknd and frequent co-star Future, who brought Abel Tesfaye into his trap universe on past collaborations like “Low Life” and “Comin Out Strong,” and returns the favor by contributing to The Weeknd’s synth-pop fantasia here. “Double Fantasy” has plenty of double entendres built around a juicy, radio-ready chorus, but works because both A-listers sound especially engaged on the track, making a bid for another hit rather than tossing out a loose soundtrack single.
