[1] Prior to Eurovision, "Pe-o margine de lume" was promoted by a music video and live performances in Greece, Moldova, Ukraine, the United Kingdom, Belgium, Spain and Cyprus.

Additionally, four reserve entries—"Brasil" by Tom Boxer featuring Anca Parghel and Fly Project, "La storia della pioggia" by Inesa, "Run Away" by Cătălin Josan, and "Vânt de vară" by Monique—were appointed in case of disqualifications or withdrawals.

[9] While 3rei Sud Est also took back their entry "Vorbe care dor", "Your Love" by Paradise was disqualified from Selecția Națională for having been played on a television show prior to TVR's cutoff date of 1 October 2007; "La storia della pioggia", "Run Away" and "Vânt de vară" replaced the three pull-outs.

[18] The combined jury and televote result was as follows:[13][17][19][20][21] The second semi-final on 16 February was held at 19:10 (CET) and hosted by Vrabete and Alina Sorescu; Nane had been replaced by the latter due to health problems.

[24] The combined jury and televote result was as follows:[20][21][22][23][25] The final on 23 February was held at 19:10 (CET) and hosted by Vrabete and Sorescu, while Iuliana Marciuc interacted with the participants in the green room.

For diversity, the jury rating the entries presented during the event was partly replaced: Titus Andrei, Dani Constantin, Dida Drăgan, Cristian Faur, Florin Ionescu, Mihai Pogășanu, Sebastian Secanu, Victor Socaciu, Tatiana Solomon, Dan Teodorescu, Flavius Teodosiu and George Zafiu.

Consequently, the originally eliminated "Fight for Life" by Nico was appointed as a replacement, however, the singer turned down the offer since she decided to compete in the contest with only her fellow entry "Pe-o margine de lume".

[21] Ultimately, "Zamira" was voluntarily withdrawn due to schedule interferences, resulting in "Te iubesc" by Adrian Enache being planned as a replacement; with him also being unavailable for the final, "C'est la vie" by Yanna was given the last wildcard.

[30] Furthermore, TVR was accused of conspiracy and it was claimed that "Pe-o margine de lume" had been played on Romanian radio prior to the broadcaster's cutoff date for Selecția Națională.

[31] Amidst plagiarism allegations in regards to "La magia del corazón" (2002) by David Bustamante, TVR decided to set up a commission for analysis;[32][33] the claims were ultimately rejected.

[14] Uploaded to the official YouTube account of Cat Music on 18 March,[35] the clip was shot by Petre Năstase at a virgin beach and in an abandoned stone pit.

[37] In April, the duo was invited to the Chișinău television show Epicentru broadcast on Euro TV Moldova to present their music video and give details concerning ongoing promotional endeavours.

[38][39] In the United Kingdom, "Pe-o margine de lume" was performed at the UK Eurovision Preview Party held on 25 April in London's Scala club.
