I actually think Sinead's song is probably the best one that has come out of the academy, it's a good rock/pop song that should appeal to lots of people.
Unfortunately, we've had SO MANY reality stars on the tv recently that Sinead is probably suffering from reality overload! People are not buying because of the "reality" factor.
Sad really, because she could be a star, I hope she continues to work and shake off the reality tag.
