Fox’s The X Factor has declared this The Season Of The Contestant (after having little luck when it focused on its revolving door of judges). NBC’s The Voice, which has been thumping X Factor in the ratings, announced today, meanwhile, that Cher, Ed Sheeran, Ryan Tedder and Miguel have joined the show as this season’s “advisers.” Cher will work with coach Blake Shelton; Sheeran with Christina Aguilera, Tedder with Adam Levine, and Miguel with CeeLo Green. “This group of wildly successful musicians will add their distinctive talents to their respective teams,” NBC’s alternative programming president Paul Telegdy said Monday. “I know Christina, Adam, CeeLo and Blake are very much looking forward to having them come aboard.”

For the uninitiated: Sheeran’s debut album + was certified 2x-platinum in the U.S. and the album’s single “The A Team” was nominated for Song of the Year at the most recent Grammys. Tedder is founder of OneRepublic and producer of artists such as Adele, Beyonce, Leona Lewis, Maroon 5 and Carrie Underwood. Miguel’s sophomore release, Kaleidoscope Dream, featured his third U.S. #1 hit single “Adorn”, which garnered his first Grammy for best R&B song and resided at the #1 spot on the R&B/Hip-Hip Airplay chart for more than 23 weeks. In April, Miguel was the musical guest on Saturday Night Live and was also included as one of Time magazine’s 100 Most Influential People. And Cher is, well Cher.

The Voice was last season’s No. 1-ranked unscripted series in the demo – the first time in a decade any series had topped Fox’s American Idol in that derby. Last June’s fourth-season finale also clocked the franchise’s biggest audience yet — 15.6 million viewers. The X Factor was last seen eating its dust.
