Don't Wanna Know

On October 11, 2016, Maroon 5 announced a single "Don't Wanna Know" featuring Kendrick Lamar, would be released worldwide at midnight on the following day, October 12.^[5] Previously "YOLO" by The Lonely Island featured the band's lead singer Adam Levine as well as Lamar.

"Don't Wanna Know" is written in the key of G major in common time with a shuffling tempo of 100 beats per minute. The song follows a chord progression of CMaj7 – D6 – Em7 – Bm/E, and Levine's vocals span from D₄ to C₆.^[6]

The song received mixed reviews by music critics. Mike Wass of Idolator stated "there's nothing bloated or excessive about the finished product. In fact, this is a case of less is more. [Don't Wanna Know] freshens up Maroon 5's sound and goes HAM on the repetition (the cornerstone of hitmarking circa 2016) — all but guarantees the band a smash hit in the process. Kendrick's verse feels like an afterthought, but apart from that, this is hard to fault."^[7] Vulture's Halle Kiefer said "it'll be on the soundtrack to every car commercial, Target ad, and drunken breakup you flounder through for the next three months" and went on to say "Don't Wanna Know has a distinctly non-Maroon 5 sound, putting a breezy, bouncy, lighthearted spin on drinking to forget, and dancing to dull the pain of losing the one true connection you ever had."^[8]

"Don't Wanna Know" was number one on the US iTunes chart after its release.^[9] Since its release, the song debuted at number 56 on the Billboard Hot 100 on October 29, 2016,^[10] and jumped to number 9 in its second week on November 5.^[11] It later peaked at number 6, becoming the band's 12th and Lamar's third top ten hit.
