Really, neither, but Ke$ha has a few good songs here and there, at least.

I'm not a fan of her, but Kesha really sucks.

Neither. At least Katy has class.

Neither..

But if I had to pick, Katy Perry is 1000x times better than kesha

Katy Perri has a much better singing voice.

Defo better than Ke$ha IMO.

Hate them both.

Kesha has quite a good singing voice for a pop singer in my opinion. Probably even better than Katy's. I think I like Kesha better than Katy after watching Katy's link Kesha, on the other hand, is not as bad as people think she is, even though her album is heavily auto-tuned. One of her performances that I like: link (Also, if you think she's lip-syncing here [@0:25], well, she's not. She has back-up singers there.]

</edit>
And this vid too-link No autotune here too. Just the extra sound effects and her back up singers. She isn't as bad as most people think she is.

I just don't think Katy has a good voice.
