chopz makes beats
charlie sheen
you do what u gotta do to get the sound u wanna get. i dont really care if i gotta loop something, chop it up and re-arrange, or compose.
A perfect example is "The World is yours" by Nas. Listen to "I love music" by ahmad jamal and when you find the sample tell me if it was in any way shape or form lazy to take that part of the song and give it a whole new existence. Sometimes things call to be looped, you said you liked Dilla some of his craziest beats were loops, "One Beer" by Doom is a loop, but its a genius one done by Madlib. At the end of the day the only question that should matter is "Does it sound good?"
I know it might seem easy to point the finger at a producer with such great commercial success as Kanye West as being lazy with his samples but if you actually think that sample in particular (Touch the Sky) is lazy than maybe you need to learn more about the practice of sampling and what it takes to achieve that sound.
