Cherri V Swag Jacking Or Creative?

So I'm compiling my list for Hump Day Music and I came across an artist named Cherri V, and I noticed that her song "Til The Sun Comes Up" sounds like Amerie's "1 Thing" and Nirvana's "Smells Like Teen Spirit". Nonetheless Cherri V's song is hot. Let me know what you think.

First listen to Cherri V:


Next listen to Amerie:


Now listen to Nirvana:


Any Thoughts?
