Grimes has revealed in a new interview that one of her songs, ‘California’, was written while she was “cosplaying” as Taylor Swift.While speaking to K-pop girl group aespa for Rolling Stone’s Musicians on Musicians series, Grimes and the group exchanged their thoughts on technology and AI in music and more. aespa’s Giselle asked Grimes how she came up with the sounds of her 2015 songs ‘California’ and ‘Easily’, adding that she loves both tracks.“‘California,’ I think I was just doing Taylor Swift cosplay, but it’s also vaguely about how the media is obsessed with portraying you as this troubled soul or something,” Grimes said in response to Giselle’s question. “I don’t know if you guys get that the same way in your media.”Elsewhere in the interview, Grimes was asked by aespa member Ningning if she was preparing for a new album.
