Composition
"Hey QT" is a dance-pop song composed in the key of F major, with a tempo of 129 beats per minute. Its production uses synthesizer melodies and an irregular beat comprisedof [sic] staccato snare hits. It features a call and response hook of "Hey QT! Yeah?". Although Dunham portrays QT, the song's vocals are actually by British singer Harriet Pittard, who also records as Zoee. Her voice was shifted to a higher pitch, and the song has a girlish, cute aesthetic. She said that the lyrics describe a "feeling of sensing someone's presence even when they are not in the same physical space". "Hey QT" includes a metanarrative about the song itself.

Release and promotion
The song was debuted at a Boiler Room show in Los Angeles promoting Hudson Mohawke's Chimes EP. A digital broadcast by Eric Wareheim opened the performance. Dunham performed the song as QT, opening the act by sitting down and reading a fashion magazine while a voiceover endorsed the QT energy drink. Dunham then lip synced "Hey QT" while appearing disinterested.

Diplo premiered his remix of "Hey QT" on 6 March 2015 through Annie Mac's BBC Radio 1 show. His reworking is more subdued, with a drop leading into the chorus. The remix was made available as a free download on WeTransfer.
