Rachel Platten has experienced a lot in 2015 – from performing her uplifting anthem “Fight Song” on “Good Morning America” to enjoying cupcakes emblazed with her face.

“Which I didn’t even know you could do!” exclaimed Platten of the dessert, which friends at her record label served for her birthday last week. “It makes them more delicious.”

Everything has to taste better for the New England-born singer these days. Platten dropped her first album in 2003. Her next release came eight years later. Both were recorded independently from a major label. Then Platten, “Fight Song” in tow, shopped around her and the track from label-to-label. I jokingly mention that she “may have heard ‘no’ a few times;” rightfully so she quickly dismisses this.

“I think I’ve been rejected by probably every single person in the industry,” she responded, with little sense of hyperbole in her tone. “But I just won’t give up. I don’t know. I have this crazy little thing in my head that won’t quit.

“I didn’t care. Of course it hurt, but something in me just wouldn’t let me stop. I felt like I had this message to give the world.”

So did Columbia Records, the label that signed Platten and released her Fight Song EP. In addition to the “GMA” performance, Platten is enjoying her greatest chart success yet. “Fight Song” peaked last week at 11 on the Billboard Adult Pop chart; it’s been on the chart for 11 weeks.

“As I spread this message, I get the privilege of listening to other people’s struggles and what they’re working on overcoming, and what I’ve found to be so true is that we all have something,” she said. “Sometimes we’re shy about saying it publicly; sometimes we don’t want to declare it. But when you do there’s this power that comes from that, and you get this rush of love and support from your friends and family.”

And that rush will probably continue through the summer for Platten, as she tours in support of co-headliners Colbie Caillat and Christina Perri. The “Girls Night Out, Boys Can Come Too” trek kicks off at Mohegan Sun Arena in Connecticut on July 10.
