The other day in school my friend said Katy was a "really good singer" and I dropped my books in the hallway. then she goes on to say "I never heard her sing live", so that was a sigh of relief..
I would say she is. Even though Ke$ha is a mess live sometimes, she's not really trying to "sing". Rihanna used to be a bad performer, but this era she's stepped it up tremendously and shown people she has potential to be an overall great performer and she was always great on tour.
It was just a bad show. Shes a good singer! She just needs more work on her singing. Katy has grown much better since she started as well. Id like to see some of you even attempt that. Im sure it wouldnt be so good
