The title track of Charli XCX's second album, the song is the British songstress' way of getting one over on all those in the music industry who initially didn't believe in her. "It's about all the people who have doubted me," she told The Metro. "It's me giving the finger to anyone who has questioned my validity as an artist. "
"That song is really fun for me to sing and I always flash my pants on it," Charli added. "It's all just personal situations and things that have happened to me."
Charli XCX told Billboard magazine: "I didn't fully get my voice across until Icona Pop's 'I Love It,' but no one really knows that's me [singing on the song], so I felt kind of mad and channeled that anger into Sucker."
