Ariana Grande at Sleep Train Arena

06SUNSleep Train Arena, 7:30 p.m., $52-$468

Things I learned while listening to Ariana Grande all week include: You need a good girl to absolutely, truly blow your mind. Bad girls won't cut it. They're apparently the new basic. Also, a girl always wants to go home with you one last time. Even if you're a jerk. But be ready: After, she's gonna break free, because she'll have one less problem without you. I know, this was a grande knowledge drop—especially for a dude long out of the dating scene. But then I listened to “Right There,” Grande's single with her ex, Big Sean. I call bullshit! This young diva can't be trusted. One Sports Parkway,
