For me, the three that continuously stand out are Sasha Allen, Judith Hill and Michell Chamuel. The rest are technically competent but bland. Far weaker crop than last year.
Even if Shakira somehow thought her growling rocker should sing a boy band song, why that one? One whose melody sounds super-weird if it's not sung by at least two different people.
These are pretty much my feelings as well. Michelle is my favorite, then Judith, then everyone else is just okay after that.
