If you don't have the courtesy to clear a sample when you have a legal team and label to do it for you then DON'T USE IT in the first place OR release the song as a free download, giving credit for the sample.
Sampling without crediting the original artist is musical fraud - selling something you're marketing as YOUR OWN and ORIGINAL when it's someone else's.
