She is super inspirational. Her song firework really helped me through tough times when my ipod died. Her chorus for firework is so magical when she rhymes boom boom boom with moon moon moon, i die of happiness. Also you you you is rhymed with moon moon moon. Lastly, she tops it off with rhyming ah ah ah with ah ah ah.

A female singer who kissed a girl and liked it and who thinks you're gay...

Some girl who cannot write songs to save her life.
Sure, she may have a "good" voice, but her lyrics make me want to punch people out.
"I kissed a girl and I liked it!" Whoop-de-fucking-do. It's amazing how people can even call her a musician.
She needs to quit writing songs like "I Kissed A Girl" and "Ur So Gay" because:

1. They are so incredibly stupid and they actually make me want to go on a killing rampage.
2. Someone is bound to get offended.
3. They still really make me want to kill people.

Katy Perry is proof that the world is coming to an end.

Proof that mainstream music audience are idiots with little regard for quality.

A singer that depended on explicit sexual themes to boost her popularity.

A shining example of all that is wrong with the modern music industry.

An American recording artist who sings about lesbian relationships, manic depressive disorder, getting married while drunk, and sex on the California beach.
