The following year, New Years Day hit a career milestone and performed at the 2017 Alternative Press Music Awards (APMAs) with legendary guest rock vocalist Lzzy Hale. The band also headlined the 2017 Vans Warped Tour alongside other main stage acts like Bowling for Soup, Falling in Reverse and CKY. On June 1, 2017 it was announced they would be included in the seventh installment of the Fearless Records compilation "Punk Goes Pop", covering Kehlani's "Gangsta" from the movie Suicide Squad. The album was released on July 14, 2017. After completing a month-long festival run with Halestorm on the 2017 "Halloween Scream Tour", both Valentyne and Ingram quietly parted ways with the band. On January 26, 2018, the band released their latest EP 'Diary of a Creep', consisting of their own song 'Disgust Me', a cover of New Order's 'Bizarre Love Triangle', a cover of Pantera's 'Fucking Hostile', a cover of Linkin Park's 'Crawling', a cover of Garbage's 'Only Happy When It Rains' (featuring fellow rock singer Lzzy Hale) and a cover of No Doubt's 'Don't Speak'
