 I had never intentionally listened to much Charli XCX music before a few weeks ago. I mean, I knew the highlights. Boom Clap was a huge hit. She was on I Love It, the awesome dance song she made with Icona Pop. And I did love Speed Drive, her contribution to the Barbie soundtrack last year. But she's never been someone I've listened to full albums by or really taken the time to appreciate. And then this summer, I started seeing the lime green cover for her latest album, Brat, everywhere.
