In December 2017, Miller stated he had retired the channel to focus on his music career, under the name Joji, producing more nuanced and serious music, releasing the EP In Tongues, which peaked at number 58 on the Billboard 200, and his debut studio album Ballads 1, which reached number 1 on Billboard's top R&B and hip-hop chart in November 2018. With this, Miller became the first Asian-born artist to do so.[19] Miller's music has been described as a mix between R&B, lo-fi and trip hop.
