Pop Corner: You’ve got a friend in Katy Perry

Track of the week: The Other Boys by Nervo

Nervo have roped in Kylie and Jake Shears from Scissor Sisters to add some glitter to this jilted lover-themed track. And it works. A shimmering slice of disco, The Other Boys builds and builds before cascading into chorus. Whether it's a super club in Ibiza or simply the local disco, this one's a keeper.

Hero of the week: Katy Perry writes songs to show support to her fans. She told BuzzFeed that "when I write songs, stuff like By the Grace of God, which is a ballad I got to do on the Grammys, it's about me having really dark thoughts about my own particular life. And even though it doesn't make me comfortable when I talk about that, I think other people hear it and go, 'Oh, I'm not so alone in my own problems. I'm not the only person going through this situation. Even someone like Katy Perry, who looks like she has it all, she still has stuff that she has to deal with. So I'm not alone in my situation.' I like when people don't feel so alone, and I like to lift people up."

Lovelorn of the week: Ed Sheeran is looking for love. He told the Mirror: "My parents are so in love it's ridiculous. I kind of look at it like pressure. They've cracked it and my grandparents cracked it, but nowadays it's harder to find that. I hope to have kids."

Zero of the week: That would be a girl who doesn't like 5SOS, according to, well 5SOS. Luke 5SOS described to Access Hollywood what he looks for in a partner. "Someone that likes the band would be nice because, I mean, that's hard to find someone that likes these three dudes. There's not many people that do. It's kind of our life. It's like having three, I don't know what to call you guys."
