They sound somewhat similar but it definitely is not sampled. Just a starving artist looking for a cut from a superstar. It's completely legal to even hear something, then totally start from scratch and have it resemble it. The trouble comes when you physically place a piece in your work and try to modify it or add to it without permission. She should win this case. If not, then rap may hit a wall soon because literally every flocka, montana, and ace beat be sounding the same anymore.
Some people always hating. Just because it shitted on your shit, you wanna get a piece now fuck you! Many people sample shit and the people need to stop bitching about it.
