Hearts Sold Separately

Mariah the Scientist drops her fourth studio album, Hearts Sold Separately, on August 22, 2025. Distributed through Buckles Laboratories and Epic Records, this project arrives as a direct follow-up to her 2023 hit To Be Eaten Alive. The record leans into neo-soul and R&B, pairing lush, retro-inspired production with raw, gritty lyrics about toxic relationships. Critics describe the sound as "chilly," envisioning a frozen landscape while wrapping personal pain in polished hooks that blend smooth vocals with intimate storytelling.

The album runs approximately 35 minutes and features ten tracks according to streaming metadata, though promotional materials sometimes reference a larger scope depending on the edition. It debuted at number one on Spotify and secured top positions on major streaming charts immediately upon release. Pitchfork highlighted the emotional depth and cohesive sound of the record, praising Mariah for turning vulnerability into universal anthems with an unflinching look at modern romance.

Commercial success quickly translated to the touring circuit. Mariah announced the global "Hearts Sold Separately Tour" in September 2025. By February 2026, the tour had gained significant momentum, kicking off with sold-out shows in Miami. Performances continued through North America and Europe, with setlists confirmed from stops in Paris and New Orleans throughout early 2026. In a June 2026 interview, she discussed the album's themes of "cutthroat" love and revealed her most vulnerable song. [edit]
