There's a bunch of billboards in my area of some old, fat, bald guy real estate agent with the lyrics to this song plastered all over it. It's about as appropriate as a Republican using a Bruce Springstein song for their campaign.
Also, isn't that the original vocal track on the chorus? I'd be expecting a cease and desist if I were this person...
Yeah, she spliced pieces of the actual song in with her "parody".
I would say she's lazy, but she made this whole video, and I would say she at least recognizes that she can't sing, but she bothered singing 70% of the video anyway.
What's funny though is that this song is so electronically raped with autotune that it doesn't sound that much different that her crappy recording.
