Though not on the album, MGK recently revealed that he and YUNGBLUD recorded three songs that will come out on a deluxe version of TTMDF later this year. The album was produced by blink-182's Travis Barker and includes a song featuring Halsey. MGK and Barker plan to perform the album in its entirety during a special livestream from The Roxy next week.
