Growing up, Reyes listened mostly to rap, and through his mother, some English-Spanish music, such as Shakira. He studied english since he was a child, on 2018 he started making music in the both languages he knew.

On december 2019, after Juice WRLD passed away, Grey Dye published on social medias he wouldn’t write no more spanish songs. He decided that he would write everything in english and if he wanted to publish spanish songs he would translate the ones that he wrote. And started recording using the freestyle technique.
