Five songs faced the votes of five regional juries and a public televote, ultimately resulting in the selection of "Playing with Numbers" performed by Molly Sterling as the Irish Eurovision entry.

Performing during the show in position 2, "Playing with Numbers" was not announced among the top 10 entries of the second semi-final and therefore did not qualify to compete in the final.

Ireland holds the record for being the only country to win the contest three times in a row (in 1992, 1993 and 1994), as well as having the only three-time winner (Johnny Logan, who won in 1980 as a singer, 1987 as a singer-songwriter, and again in 1992 as a songwriter).

In 2011 and 2012, Jedward represented the nation for two consecutive years, managing to qualify to the final both times and achieve Ireland's highest position in the contest since 2000, placing eighth in 2011 with the song "Lipstick".

[1] From 2008 to 2014, RTÉ had set up the national final Eurosong to choose both the song and performer to compete at Eurovision for Ireland, with both the public and regional jury groups involved in the selection.

[2] Eurosong 2015 was the national final format developed by RTÉ in order to select Ireland's entry for the Eurovision Song Contest 2015.

Following the 50/50 combination of votes from five regional juries and public televoting, "Playing with Numbers" performed by Molly Sterling was selected as the winner.

[16][17] The backing vocalists that joined Molly Sterling on stage were Jessica Supple and Naomi Clarke, while the three musicians were: Jimmy Rainsford (drums), Darren Sweeney (bass) and Póilín Lynch (cello).

The jury consisted of five music industry professionals who were citizens of the country they represent, with their names published before the contest to ensure transparency.

This jury was asked to judge each contestant based on: vocal capacity; the stage performance; the song's composition and originality; and the overall impression by the act.
