Eminem has asked Republican presidential candidate Vivek Ramaswamy to stop using his music after the entrepreneur performed the rapper’s song “Lose Yourself” earlier this month at the Iowa state fair. Attorneys for BMI, a music rights company, said Eminem had removed his music from the company’s license with Ramaswamy’s campaign, according to a letter obtained by Billboard. “BMI will consider any performance of the Eminem works by the Vivek 2024 campaign from this date forward to be a material breach,” the letter reads.
