That songs needs an attitude. Siobhan was just jumping around like a mental patient. She needs to go back in the oven for a couple of years and then come back to singing professionally.
That song was all over the place. She had no clue how to sing the style. She even tried to bring it subregister and had no idea where the pocket was! She blew it big time! She has the voice and singing ability, she just doesn't have the maturity to understand what makes her a good singer. There is a world of different between her Hollywood week, "Living For The City" and almost everything else she did. It would be interesting to find out if someone was influencing her, or did she conjure all that crap singing/song choice on her own?!
I won't miss here now. I'll miss seeing her sister sitting in the audience before I'd miss Sioscreech!
