According to a Grammy insider Nas submitted the following
Kings Disease 3- Best Rap Album
Michael & Quincy- Best Rap Song, Best Rap Performance
One Gun One Mic- Best Rap Song, Best Rap Performance
On My Soul- Best Song Written For Visual Media
So its like I predicted, Nas and his team decided to go with KD3 as its the more Grammy leaning album and both KD1 and 2 were also nominated. I’d like to see Michael & Quincy get a Best Rap Performance nod as Nas rapped his muthafukking ASS OFF on that joint and it would be ironic if One Gun One Mic got into Best Rap Song considering that its technically a Magic 2 track (and the whole “relevance” argument would be a fun sticking point to jab at the fukk Nas Coalition)
Overall these submissions are very strategic and I can realistically see him getting into at least 3 of those 5 categories (Best Rap Album should be a lock for a nom, then M&Q for Best Rap Performance and One Gun One Mic for Best Rap Song)
