I can't say I'll miss Belle Amie; I could never get away from the idea that they were four fairly average soloists who didn't really want to be in a group, but took the option they were given. Also it's hard to take a band with the same name as a porn studio seriously.
I think Wagner's probably got another week to go before the voters get bored with annoying Simon. Cher did herself a lot of good by doing a ballad - her raps and mash-ups are all very well, but the winner's song is always a ballad with a big key change; she needs to prove she can deliver with that kind of material too. I don't have a particular favourite but Rebecca is looking like an increasingly strong candidate to win.
