FOX's singing competition, The Four: Battle For Stardom, is truly "all about that bass."

In this week's episode, the contestants are being mentored by Grammy Award-winning artist and judge Meghan Trainor. "I'm just gonna talk to her about all of her experiences, [and] try and get some wisdom from her," James Graham said — and he, Noah Barlass, Ali Caldwell, and Sharaya J do just that.
