I really have no idea who will win. Other than it won't be Adam Levine's guy... what with Christina Aguilera totally hating him (did anyone else see her TEXTING and looking at her nails during his performance?? Why does she hate him so much??) and the horrible song choice of "99 Problems" (doesn't he understand who votes?? Middle-aged women!!!) I don't think he has a chance.
The other 3 are pretty awesome. I think I like Jermaine the best but Chris Mann is pretty awesome... kind of like the next Josh Groban maybe? Not nearly as good as Josh Groban but I can see all those middle-aged ladies picking up the phone for him.
