"Reġina" was produced by Boban Apostolov and features lyrics in three different languages: Maltese, English and Spanish.

[3] The song was described as "one of the favourites" to win the competition by Giulia Magri of the Times of Malta and as the "straight-up winner from the get go" by Culture Fix but was disqualified from the competition due to unauthorised social media posts.

[4][1] Aidan was later asked to perform as an interval act during the final of the national competition under the condition that he did not sing his disqualified entry.

[2] On 12 February 2023, a day after the national final, Aidan made the song available on streaming platforms and released a live performance video in which he wore the designer outfit that he would have worn had he not been disqualified.

[6][7] Culture Fix praised the song's "pulsating grooves" and Aidan's "confident vocal turn".
