Kara, because she is so gorgeous!
I know that it's kinda hard to know her by rep, since songwriters are more obscure in a song than the bassist in a band, but she wrote the first track of Miley Cyrus' 2nd CD, the Hannah CD, and it's a very catchy song. She is very creative!
It's kinda intriguing to see her give technical advice, since writing a pop song is all about chorus.
