All Time Low recruited Mark Hoppus and Joel Madden as guest artists. The band is due to go on a headline tour in the US after the album release with Tonight Alive, Issues and State Champs. A February 2015 co-headlining UK tour with You Me at Six was previously announced, and All Time Low sold out a headline a show at Wembley Arena in March as well as appearing at the Soundwave music festival in Australia.

Piece by Piece sees Clarkson reuniting with frequent collaborators Greg Kurstin, Jesse Shatkin, Jason Halbert, Eric Olson, and Chris DeStefano. Her pregnancy hurdled her efforts to write more than five songs for the album. As such, she gathered material from songwriters such as Sia, Matthew Koma, MoZella, Bonnie McKee, David Jost, Semi Precious Weapons lead singer Justin Tranter, and former Cobra Starship member Ryland Blackinton, among others.
Swift began preparing for the album during the same year that Red was released, and during a significant amount of media scrutiny. Over the course of the two-year songwriting period, she primarily collaborated with producers Max Martin and Shellback—Martin served as the album's executive producer alongside Swift. The album's title was inspired by the pop-music scene of Swift's birth year, and its musical content represents a stylistic departure from the country pop of her previous albums.
In contrast to Swift's previous work, the production of 1989 consists of drum programming, synthesizers, pulsating bass, processed backing vocals, and guitars.
