A so called "singer" with a very annoying voice that sounds like nails on a chalkboard.

The new {s}hit "umbrella" by Rihanna made me want to trip her with one.

Quite possibly the most untalented artist of all time. Really has no business in the music industry in the first place, see her singing live or better yet her singing er butchering Mariah Carey's "Hero" via YouTube. Each song she makes is worse than the one before.

Rihanna is a horrible singer and has no talent and should just go away. She is ruining American pop music every time she sings.

Proof that you don't need talent to become famous. Horrible singer of horrible songs. Should just go away forever

If I hear that damn Umbrella song one more time I'm gonna knock someone out. And it might just be Rihanna herself

FeFe Dobson knockoff.

The Bitch is trying to sing like her in her new lame ass album "Rated R". Hoe please. I hope FeFe whoops her ass.
Rihanna is NOT original. Get it through your heads.
