This one is probably a no brainer because the only change to this was the speed and drums. Another obvious sample since very little was done to it.

Curtis Mayfield was probably one of the most talented soul singers/ producers to come out of his era. He had hits in the 60s with the Impressions, and in the 70s as a solo artist. He always had meaningful lyrics about pride, love, and the struggles of life. This sample was taken from another great soul album of the 70s. An album that has a clear message and can be played without skipping songs. How many albums can you say that about today? One more thing, study those drums! You have to remember this was done well before drum machines and the like. These drums are sick!
