[3] To support it, they simultaneously released its lead single, "Tejano Blue", and announced that they will embark on the X's World Tour throughout 2024 and 2025.

The musician revealed how he actually had to "write" and "sing" about a loss (of a four-year relationship), instead of just talking about it which would simply "scratch the surface".

[11] Writing "Tejano Blue", its second track, it was inspired by Gonzalez's life in his hometown, El Paso, Texas, as well as Selena's "Como la Flor" and Cocteau Twins and "somehow" tried combining the sound of both artists.

[3] "Hideaway" focuses on a specific moment in Gonzalez's life, when he and his girlfriend went to a beach near Marina del Rey, California to let their problems fade away.

[17] In a positive review, Tom White of The Independent proposed that X's is "made for late-night headphones moments" and added that it "shapes up to further cement [Cigarettes After Sex's] appeal".

[20] Heather Phares of AllMusic suggested that the album "frequently feels like some of their most personal work" and added that it "delivers enough glamorous brooding to keep fans happily miserable".
