After two years of legal struggles, rapper YNW Melly continues his musical career with second studio album (and fourth full-length release), Just a Matter of Slime. Pieced together primarily by his label while Melly was incarcerated and awaiting trial, the project features old vocals from the pre-2019 vault -- and as a result, the album's features tend to take the main stage. While his debut album, 2019's Melly vs. Melvin, was a relatively independent piece, Just a Matter of Slime sees him link up with a wide range of collaborators: Lil Uzi Vert provides a sleek sparring partner on "Mind of Melvin," Lil Baby and Lil Durk offer radio-ready shine on "Take Kare," and Future and Tee Grizzley give the "Freddy Krueger Remix" some gritty traces. Unfortunately, Melly's own vocals don't quite match the energy of his contemporaries (perhaps due to his lack of input in the final release) and as such, much of the album lacks the outlandish personality that made him so popular in the late 2010s. When combined with uninspired and sonically incohesive production, these tracks result in a lethargic layover tape, rather than a second full album.
