ImageSead “Diddy” Combs knows the struggle. Yet another new singing competition show means there’s yet another new format and set of twists to figure out. Knowing how much brain power should be reserved for more pressing matters (hello, nuclear buttons!), Combs has found a way to distill the essence of Fox’s “American Idol” successor, “The Four: The Battle for Stardom.”“It’s like ‘Game of Thrones,’” Combs told reporters Thursday at the Television Critics Assn. press tour in Pasadena. Combs, who was joined onstage by fellow show judges DJ Khaled, Meghan Trainor, music executive Charlie Walk and host Fergie, kept his metaphor going: “You get to challenge and if you want to chop somebody’s head off to get the seat. It has that vibe.Got it?For what it’s worth, he isn’t the first to try the “Game of Thrones” comparison. Rob Wade, Fox’s head of alternative programming, also drew that same connection last summer, though he suggested there was “better singing and less nudity.” Tomato, tomahto.For those who like synopsis straight up: The show starts with finalists. Each week, the top four singers will sing against challengers, which could include viewers, to keep their spot on the show. The panel of experts select the original finalists from auditions, and, as things progress, help to shape the winner’s career.But do fans of the music competition genre have any more room for another show of this ilk? The judges say yes."Because there's always a dream,” Combs said. "This show is different. In the drop of a second, you could just lose your seat.”Added DJ Khaled: "You can't put a cap on success in talent. There's new talent that's coming out every day. This is music we're talking about. Music's forever. It's forever."“The Four: Battle for Stardom” begins its six-week rollout Thursday at 8 p.m. on Fox.
