I was disappointed in both her singing and the way she went back on her implied promise to back off the screaming. I like her, I want to see her last a very long time on this show and make it all the way to top 3 if not win the whole thing. However, I may have to withdraw that if she doesn't stop with the screaming.
I hated it when Adam did it and I was willing to cut Siobhan a lot of slack because at least she was doing it when it was appropriate for the song, however, last night? Not appropriate at all and completely ruined her performance.
Hopefully she learned a lesson and will do better next week.
I'm afraid she may be self-sabotaging due to being so "green" and not knowing her "voice" enough to be true to it like Crystal and Mike and even Casey are doing. It's times like this that her inexperience compared to those three really shows.
