It actually is a little worse than some of the other top 40 stuff, because it's less polished. Kesha shows zero talent (from what I've heard), but at least it sounds like someone worked on the track, or she tried to keep her lyrics in the beat (not that that's difficult when your beat is just one single note on and on and on). This is really terrible.

EDIT: Now that I've read the article, I can see why. This was a vanity company making it, essentially ripping off teenage girls and their mothers. Now I feel kind of bad that this is going on with her. Though the article notes she's doing an acoustic version, so hey, maybe she can sing--but she'll be singing the same shitty song and shitty lyrics.
Which apparently she did not write, so yay Ark Music Factory, you fuckers. If you're gonna charge kids and their moms for making your shitty auto-tune videos, at least try to write decent music.
