Music has gotten to the stage that trained musicians that create, will be criss crossing patterns, rifts & scales. There will be sections that will vaguely be familiar to other works.To some genres, sampling is unacceptable and lacks creativity but tolerated. From what I have been made to understand, it is paying homage to the works of other artist. All the labels have to do is, just make sure that permission and the rights of others are not infringed and in my view.
Quite a few masterpieces have been produced out of sampling, if that is Mr.West's style he is talented, either listen to his work or don't. Very few if not all will embed a sample into their production.
The creative and genius aspect of it is, placing it together in a timed format and making it work. The masses care less once it sounds cool & placed right on queue even to the trained ear.
