Yeah theres something definitely off in this one. Makes Moka sound like he sings as bad as I do, which I know isn't true. As for the beat, its pretty repetitive. Not a lot of variation other than drops. I like what you have for it, but over the length of the entire thing it definitely is missing something to catch the ear again. For a song like this I'd say it would definitely need different sections between the rapping and the singing that plays to the strengths of them. In all fairness though unless the off key issue is fixed adding anything to it is pointless.
