"Hello" is the opening track of COLLXTION I. Although a demo of this track began circulating on the web in 2014, the finalized version was released with the EP in April of 2015. The song contains elements of 80s synth pop, and a theme of love and a fresh start with someone new, as explained by Allie herself: "The delusion of love and the comedy in the idea that you can be rescued by someone. It all seemed ridiculous to me at the time I wrote it. I pictured a bride in a straight jacket white dress." .
