Oh god...
This is practically another "Justin Beiber" thing, except there's few who ACTUALLY love her music.
So, everybody hates, mean things are said, bad jokes are made, simples.
On the other hand, the worst song I have ever heard has changed from "boom boom pow" to "Friday"
Unless it's done by
Bob Dylan (<link)
I swear. It makes me want to curl up in a ball and die, it's possibly the worst thing I've ever had to listen to.
My 15 YO friend (<link) does a better job then that, without ANY autotune -/-
Also, the song I linked, I think, is better then the original (both times

)
I can't stand her music, and in the words of Charlie Sheen
"Rebecca, we don't hate you because you're famous, you're famous because we hate you"
