One of the first statements mentioning the album was made on Twitter, following the release of the song "Never Enough", which fans assumed would be the lead single.

[10] On February 3, 2016, the song "Old Habits Die Hard" was released, originally as a non-album single available for free download, but was later included in the album's tracklist, as Allie X had promised to include the song once it hit 1 million plays on Spotify.

[11][12] During a question and answer session on social media site Tumblr, Allie X stated that the overall theme for CollXtion II would be "longing and being lost".

[13] On May 13, 2016, after the release of "Too Much to Dream", Allie X announced the project CollXtion II: Ʉnsolved, which saw her release a collection of demos and songs on Spotify over the course of the summer, in order to shortlist the songs her fans wanted to see on CollXtion II.

[14][15][16][17] The songs released through the project were "Too Much to Dream", "Purge", "All the Rage", "Casanova", "That's So Us", "Misbelieving" and "Alexandra" along with the non-album single "Old Habits Die Hard".

Out of these, only "Old Habits Die Hard", "Casanova" and "That's So Us" were remastered and included on the album's final track list.

"It feels like the beginning of something exciting," she stated in a video released on YouTube, in which she breaks down the creation of "Paper Love".

Dates were announced in New York City, Toronto, Chicago, Los Angeles and London.

[24] Before the announcement of the release date, Allie X opened a CollXtion II hotline, which would play snippets of certain songs on the album to anyone who called.

[4] Avery Stone from Noisey gave the track a favourable review, describing Allie X as "sugary-voiced", saying she doesn't "dwell on it".

[citation needed] The song includes the guest collaboration of Michigan-based band Valley Girl.
