Swedish House Mafia are back—and they’ve brought one of Sweden’s finest voices along for the ride.
The trio’s brand-new single, “Happiness Is So Sad,” featuring Lykke Li, is out now on all major streaming platforms, marking the pair’s first-ever collaboration. It’s an emotional, atmospheric track that explores the bittersweet space where joy and heartbreak coexist, capturing the feeling of looking back on moments that were beautiful precisely because they’re gone.
Produced by Swedish House Mafia alongside PARISI and Fred Again.., the song was recorded in Stockholm and boasts an impressive songwriting team including Max Martin and Oscar Holter. Fans got their first taste of the track during its world premiere with Zane Lowe on Apple Music 1 on 30 July.
The release also marks Lykke Li’s first new music since May’s The Afterparty, following a packed summer of standout performances including Coachella 2026, KOKO London and Athens’ iconic Odeion of Herodes Atticus.
Meanwhile, Swedish House Mafia are in the middle of their Ushuaïa Ibiza residency, where “Happiness Is So Sad” has already become a standout moment in their sets. The track also made waves at Tomorrowland 2026 when Steve Angello joined Sebastian Ingrosso on stage for a crowd-pleasing performance.
