Jaylein Auther-Henry Cantrell (born July 23, 1999), professionally known as YN Jay, is an American recording artist hailing from Beecher, Michigan.

YN Jay’s older brother Gabe would inspire him to start rapping age 10—recording eight to ten songs a day in his early teen hood. After Gabe’s unfortunate passing Jay would start his music career, releasing his first project MVP in November 2019.

He began to gain traction when songs like “Coochie” featuring Louie Ray and “Coochie Scout” blew up on TikTok.
