Despite mixed reviews from music critics, "Rude" was an international commercial success. The song peaked at number six on the Canadian Hot 100 and internationally topped the charts in the United States and the United Kingdom and peaked within the top ten of the charts in Australia, New Zealand, Ireland, Denmark, the Netherlands and Sweden. "Rude" was the ninth best-selling song of 2014, with global sales of 8.6 million units, and won the Juno Award for Single of the Year.

"Rude" was named after the reggae term "rude boy" and originally based on a real-life situation. The lead singer of Magic!, Nasri, had been in an unhealthy relationship with a previous girlfriend. After Nasri got in a fight with his girlfriend, the band based the song off of that headline. The couple was in a "mean time" when they were both being rude to each other, as Nasri says in what he describes as a "dark vibe." "Rude" was written by Nasri, Adam Messinger, Mark Pellizzer, Ben Spivak and Alex Tanas, and produced by Adam Messinger. According to the sheet music published by Sony/ATV Music Publishing at Musicnotes.com, "Rude" is a reggae fusion song set in common time with a tempo of 144 beats per minute. This song is written in the key of D♭ major.
