Belgium was represented by Xandee and the song "1 Life". VRT's (Vlaamse Radio- en Televisieomroep, the Flemish broadcaster) organized the Belgian National Final 'Eurosong 2004', which took place on February 15, 2004. Four preselection programmes were produced and broadcast on 18th and 25 January and 1st and 8 February 2004. All five programmes were broadcast from Studio 100 in Schelle and were hosted by Bart Peeters. The automatic favourite "1 Life" triumphed throughout the competition, which included a performance from Barbara Dex who came in last for Belgium at Eurovision 1993.

Before Eurovision, Belgium was considered the favourite to win the whole competition and received a good amount of pre-contest promotion. Xandee even sang the song in a Turkish version for a visit to Istanbul. However, the performance was considered by many as poor and flat, which may have led to a complete fail during the voting procedure. Xandee reproduced her Eurosong performance with a few minor changes, but it didn't seem to help as she only managed 22nd place with 7 points.
