I like Katy Perry to a point and how she referenced "Big Hoops" because of Nelly Furtado's song, but I'm not gonna deny that Katy Perry seems to take bits of other modern day artist's work and incorporate into her own. Towards the end of "Big Hoops" Nelly does a similar "no, it ain't over yet" but that song was released in 2012. This is just one of many examples. No hate, I have reasonable grounds for my accusations.
