I'm sorry, although i like Diana there is nothing that original about her, she sounds very similar to Dolores O'Riordan from the cranberries (check youtube) As for the comments about Alexandra, yes, there are loads of black girls who can sing alexander has a good tone to her voice and has been on point for weeks. For me this is Laura's best weeks, she didn't sing in 3 voices and was reminiscent of the girl we saw in the first audition (i know its the same song) She didn't sound like an Amy Winehouse tribute band and was more original. it's sad that Austin went home because he wasn't the worst but he does sound too much like lee from Blue and that started to irk me. Rachel... Rachel looked like older than 26 and hasn't (apart from last week) shown much star quality. Simon and co keep saying raw talent - fantasia had raw talent she needs to step it up. Daniel & Oeghan need to go the the judges keep praising the young rhythmless one. Mariah week will be a hard week. Cjeryl needs t take notes on her artists interpreting Mariah songs and not trying to be Mariah. Alex needs to be careful as she's sung Mariah already so needs to make it original as we know already that she can sing mariah songs. Hopefully this'll be the end of Daniel and Oeghan leaving room for the real artists in the making
