#3 Ke$ha
There are 2 types of singers in this world, talented singers like Michael Jackson and Celine Dion, and the ones that teens listen to. Where does Ke$ha belong to? Obviously the 2nd group. She can't really sing live, her music is FULL of Autotune. Most teens dont't care about these things. She is a horrible role model too, I mean, look at her, drugs, alcohol, hardcore parties? If you've never seen her live, don't bother. She is mostly known for her drunk and party girl image.
#1 Rebecca Black
If you haven't heard her song "Friday", you will NEVER understand why she is such a horrible singer. Her voice is flat and expressionless. The lyrics are horrible and makes no sense. It's as if it was REALLY autotuned to sound flat. To make things worse, her music video has a total of 1,396,189 dislikes!! Way more than the number of likes. Seriously you can only see for yourself how bad she is at singing.
#5 Kim Kardashian
She is just another rich celeb who wants to break into the music business. She can't sing either. Her pop career re-lauch failed as expected. She sounds like an amatue, erm, helloooo hasn't she heard of singing classes?!! If you ask me, she should really just stick to being a business woman and get out of the music industry FOREVER.
