This version of Eminem's Mockingbird is based on an Eminem Type Beat I made just the other day.
To be honest, I haven't made any Hip-Hop tracks in the last couple of years.
For that fact, it was finished quick.
The entire track was written and produced in one evening.
The rest was to put the Eminem acapella over the beats, mix the whole thing and some kind of mastering.
