Who the hell has the balls to sing the song written and performed by a judge and hope that the judge will think it's good? Didi Benami, that's who!

Didi Benami has a great voice! Simon Cowell gave her a "small yes" during her audition, but she has seemed to find confidence, poise, a guitar and a hair straightener since then and she killed it. Didi reminds me of Colbie Caillat. There's definitely room for her in mainstream music and female singer-songwriters - Lady Gaga, Alicia Keys, Beyonce and Pink are dominating the charts.

Go Didi!
