Reality shows are not Ronson's thing unless it's about drinking Jack Daniels but, I think I will give this one a chance tonight.The music begins for NBC's new vocal competition "The Voice."  Hosted by Carson Daly, "The Voice" will feature four celebrity coaches working with contestants as they try to win a recording contract and a 100-thousand-dollar cash prize.  Serving as the show's coaches are country star Blake Shelton, soul singer Cee Lo Green, pop diva Christina Aguilera, and Maroon 5 frontman Adam Levine.  Shelton says viewers will be "surprised at all the talent" that will be on display, while Aguilera recently told "USA Today" that she's eager to bring "positivity" and an "honest perspective" to the show.  Catch the debut of "The Voice" tonight by tuning in to NBC at 9:00 p.m. Eastern.
