In a 2015 interview with Time, Clarkson revealed that she had commissioned club remixes of the tracks from her seventh studio album Piece by Piece (2015) as part of their discussion of foraying into different genres—including a possible dance music album. Some of these tracks include "Heartbeat Song", "Take You High", and "Dance with Me", with the intention of releasing them to music clubs in the future. Following a successful response of her rendition of the title track, "Piece by Piece", on the final season of the television competition series American Idol on February 25, 2016, Clarkson immediately recorded a studio version of her performance and sub-named it the "Idol Version", which was released on February 29, 2016. On that same day, RCA Records announced the release of Piece by Piece Remixed on March 4, 2016, in honor of studio album's anniversary of release in the United States. Containing selections of remixed tracks from Piece by Piece, the remix album is book-ended by the "Idol Version" of the title track and a live recording of "Tightrope" at the Piece by Piece Tour as its opening and closing songs. It also contains two BillboardDance Club Songs hit singles—"Heartbeat Song:, which peaked at number one; and "Invincible", which peaked at number two.
