The first impression is that this beat is very powerful. It has a lot of bounce to it and the melody fits perfect to the drums.
Special about this beat are the breaks. They are well set and fit good to the beat. They make the instrumental more interesting and treat the melody well.
Crazy is good for every type of rap. You can either rap/sing with autotune or kick your hard bars. You can also sing over it if you can.
The beat is very well done and perfectly rounded. Nothing is annoying and there is just enough space for the vocals.
