I remade "made you look" by Nas about 5 or 6 years ago when I was first learning.
I got inspired after hearing the original sample and got to work. I was pretty proud that I figured out how to make it sound exactly the same, but at the end of the day it wasn't my beat. Needless to say, I haven't tried to remake someone else's beat since. It's a nice challenge, but it's not something I'd waste my time with nowadays
