Mariah the Scientist has emerged from her lab with a new album, “Hearts Sold Separately.” Fueled by “Burning Blue,” which hit No. 1 on Billboard’s rhythmic airplay chart and No. 25 on the Billboard 200, “Hearts Sold Separately” pensively explores love and relationships, themes synonymous with the former St. John’s University biology student.
