It is the Detroit rappers Duawn “Go Hard Major” Payne and Harrell “H Matic” James, who believe that “Go crazy” is basically identical to their song “Krazy” from 2012. They also point out that Big Sean was active in Detroit during the same period they performed with “Krazy” in clubs and bars.
“Go crazy” is on Megan Thee Stallion’s latest album “Good news”. In addition to Big Sean, rapper 2 Chainz also participates in the song. However, 2 Chainz is not mentioned in the lawsuit.
