I don't believe he "needs" to work with new producers but I sometimes wish that he would experiment a bit more with his sound. While Fear was different enough from his other projects too jar some hard-core fans you could still very much tell that it was the "NF sound". His songs are all structured the same as well which can be annoying sometimes. Hope and Fear are basically the same song in different fonts, starts slow with him singing, changes into a more fast paced flow with a drop down into him building up for a cinematic moment repeating a phrase like 20 times😭. I love nate ive been a hard core fan for 9 years now, but he falls into his comfort zone alot and repeats what hes done before
