Hip hop is based on sampling. The act of taking something else, flipping it, and making it your own. Stealing lyrics and beats should never be a problem if you understand what hip hop really is. But that's a whole different conversation for another time. Just peep the sample.
It's called "Move On Up." Produced in 1970.
The sample was taken, and sped up a bit.
Actually, I think Kanye was sued over this one... I'll cover that later.
Here's the song.
Again, "Move On Up" - Curtis Mayfield
Here's Kanye's, "Touch the Sky"
