The wait that began on a Sunday night in Ibiza is over. Swedish House Mafia and Lykke Li have released Happiness Is So Sad, the first collaboration between two of Sweden’s biggest musical exports, and it arrives with the kind of pedigree most dance records can only dream of. The trio announced July 31 as the release date on Instagram, though the studio version was already live on streaming platforms by Thursday evening, when EDM.com and EDMTunes first covered it.
The single was recorded in Stockholm by Axwell, Steve Angello and Sebastian Ingrosso together with Fred again.. and PARISI. The writing credits add Max Martin and Oscar Holter, two of the most decorated names in contemporary pop. According to EDM.com, Martin has penned the second most number one singles in the history of the Billboard Hot 100, trailing only Paul McCartney.
How Happiness Is So Sad Took Over the Ibiza Summer
Swedish House Mafia premiered the track on June 28 during their weekly residency at Ushuaïa Ibiza, and it quickly became one of the most talked about moments of their sets. Fan recordings of the drop spread across Instagram and TikTok within hours, turning an unreleased ID into a nightly ritual at the open air club. Earlier in July, Steve Angello and Sebastian Ingrosso also played it during Tomorrowland 2026, giving festival crowds a preview weeks before the official release.
The rollout fits a season in which the White Isle has dominated the conversation, from Amnesia’s 50th anniversary celebrations to the superclub arms race reshaping the island. A month of teasing on Ibiza’s biggest open air stage is about as effective as promotion gets in 2026.
A Swedish Avengers Crew
The trio discussed the collaboration in a Vogue Scandinavia cover interview published ahead of the release. “We had this idea of putting together a Swedish Avengers crew,” Ingrosso said. “Lykke is just one of the coolest artists ever,” he added. “She has this depth that we really love, and her voice is so unique.”
Lykke Li described the Stockholm session in the same interview. “When we found the riff we were all screaming with our hands in the air,” she said. “Those melodies that pierce your soul, that make you want to cry and dance at the same time. We Swedes understand darkness but we love the light more than anyone else.”
That tension sits at the heart of the record. The group built its name on euphoric anthems like Save The World and Don’t You Worry Child, while Lykke Li has spent her career in haunted dream pop. Here she sings “It’s not the rain, I’m out here crying” over a production that builds slowly, favoring atmosphere over an obvious festival drop, a bittersweet reflection on how happy memories turn heavy with time.
What Comes Next for Swedish House Mafia and Lykke Li
The single lands at a pivotal moment for both camps. Swedish House Mafia continue their Ushuaïa residency every Sunday through September 13, and the new record now has an obvious home in the back half of those sets. Then come the homecoming shows: two nights at Ullevi Stadium in Gothenburg on August 28 and 29, the biggest headline performances of the trio’s career.
For Lykke Li, this is her first new music since The Afterparty, her sixth studio album, released earlier this year. It caps a busy stretch that included performances at Coachella, London’s KOKO and the Odeon of Herodes Atticus in Athens.
Whether Happiness Is So Sad becomes a Don’t You Worry Child sized moment will depend on how it travels beyond the island. What is already clear is that a month of Ushuaïa premieres, a Max Martin pen and a Fred again.. production credit have given Swedish House Mafia their most anticipated release in years.
