Nine Songwriting Credits by Blink-182

Nine is the eighth studio album by blink-182, released in September 2019 on Columbia Records and produced by John Feldmann and Travis Barker. It is a more pop and electronic-influenced album than California, incorporating trap beats, synthesizers, and contemporary pop production that aligned the band's sound with the 2019 mainstream rather than the 1990s pop-punk tradition. Hoppus and Barker wrote all material with Skiba; 'Happy Days,' 'Blame It on My Youth,' and 'Pin the Grenade' were the principal tracks. The album debuted at number 14 on the Billboard 200 with 38,000 first-week units, a commercial decline from California, and received mixed reviews, with critics noting that the pop production innovations came at the cost of the rock energy that had defined the band's most celebrated work. Nine represents the furthest departure from the blink-182 formula in the band's career and the most direct attempt to place the band within contemporary pop production rather than the rock genre category. Nine is the most sonically adventurous attempt in the band's catalog to bridge their pop-punk heritage with contemporary production techniques, and despite its divisive reception, it demonstrated a willingness to take commercial risks that fewer acts with a 25-year legacy would have attempted.
