You need to pay attention to which sample is being credited. If it says “direct sample”, that’s a sample, a portion of the original recording is being used. If it says “replayed sample”, that’s an interpolation, a portion of the original work is being reproduced in a new work. The good thing about WhoSampled is that you can check it yourself by listening.
I wouldn’t use Genius, they’re very messy about the difference between the two and sometimes credit stuff without sourcing so you can’t really check if it’s true.
