"Pe-o margine de lume" was promoted by endeavours in Belgium, Spain, Cyprus, Moldova and Ukraine, and by the release of an accompanying music video, shot by Petre Năstase, portraying Nico and Vlad at a beach and in an abandoned stone pit.

[1] "Pe-o margine de lume" is a Romanian- and Italian-language[1][2] operatic ballad, which an editor of El Mundo likened to the works of Italian singer Andrea Bocelli.

[2] "Pe-o margine de lume" was initially recorded as a solo by Miriță in a longer version, with Nico's vocals being eventually added after the song's bridge was cut out to reduce its length.

[7] Following accusations of plagiarising "La magia del corazón" (2002) by Spanish singer David Bustamante, the Romanian Television (TVR) decided to set up a commission to analyze "Pe-o margine de lume".

[11] It was filmed by Petre Năstase during 12 hours in two locations – a virgin beach, containing "no people, no hotels [...] like the end of the world, as the song itself describes it", and in an abandoned stone pit which was about ten kilometers away.

[11] For further promotion, Nico and Vlad embarked on a supporting tour that visited Belgium, Spain, Cyprus, Moldova and Ukraine in March and April 2008, giving interviews and appearing on television shows.

[14][15] Subsequently, "Pe-o margine de lume" was chosen to represent in Romania in the contest by the same voting system, gathering 271 points in the final.

It was also claimed that "Pe-o margine de lume" was played on Romanian radio prior to 1 October 2008, the submission deadline set by the broadcaster for the Selecția Națională.
