"Giddy On Up" is an up-tempo country song, driven by fiddle and banjo with a prominent brass section in the pre-chorus.

The song's female narrator confronts her man ("Baby where you been, its half-past ten"), making note of the many signs that suggest he has been cheating on her with another woman ("Smilin' a lot when you look at your phone / There's a change in your tone").

"[3] Slant Magazine critic Jonathan Keefe also gave the single a mixed-to-positive review, praising the song's "awareness of pop songcraft and structure" and its "inventive production" for drawing favorable comparisons to the work of Big & Rich, Little Big Town, Taylor Swift, and pop producer Mark Ronson, but noting that Bundy "overdoes her vocal performance" and questioning whether the performance is played for sincerity or for camp.

[6] In the video, Bundy is shown confronting her cowboy love interest (portrayed by New York City actor and personal trainer Brian Patrick Murphy) while performing on stage in a saloon.

Bundy proceeds to intimidate him with a group of dancers performing behind her, before riding off on her horse, dragging the tied-up cowboy behind.
