Mariah the Scientist, known for her hit "Burning Blue," the song that changed everything for her career last year. The song was released as part of the Billboard Hot 100 and topped Rhythmic Airplay. Mariah credits her success to her older sister and manager, Morgan Buckles, who joined her team as tour manager in 2022. She debuted the song in full during an April 19 Howard University performance and later released it to digital service providers on May 2. The success of the song led her to collaborate with Grammy-winning Latin R&B star Kali Uchis on "Is It a Crime," which became Mariah's second consecutive Hot 100 top 30 hit. Her fourth studio album, Hearts Sold Separately, became her first full-length project to reach No. 1 on any Billboard chart and her highest-peaking Billboard 200 entry, reaching No. 11. Despite internet scrutiny over her relationship with Atlanta MC Young Thug, Mariah has remained positive and focused on her next project.
